Transcripts

a very good morning class 12th

as promised i am back

with the project ideas

i'll be doing it in three parts this is

the part one of the project ideas in

chemistry

and how to report those project ideas

the project file was my last video where

i had uploaded the sheets in which the

order in which the sheet should be and

how your project report should look like

fine so in today's

video i'll be sharing um five six five

six ideas for your project in chemistry

the first set of ideas that i am sharing

with you are related to your cation

now cation analysis is something which

should be on your tips

this part is crucial for your practicals

it gives you around eight marks in your

practicals

for your cation analysis and an analysis

so salt analysis one important part that

you need to do for your projects that i

am going to talk about today

there is an added advantage if you do

your salt analysis well you gain marks

in your

practical your viva as well as your

project you don't need to prepare

separately for your project in that case

that is the basic advantage of choosing

a project which is related to your

practicals

or to your theory because that you would

definitely be preparing

so moving on with the project ideas of

today in the part one of my video this

is sima makhijani presenting to you

project ideas the investigative project

ideas in chemistry practicals for

the year 2022

okay

now moving on to the first project idea

the first project idea that i have is

aloe vera analysis

now aloe vera these days is quite high

in demand which means your application

and daily life while a page can add on

to many things you can write out points

of medicinal benefits of aloe vera where

you will write it down the applications

in

medicinal field how is it helpful what

are the mineral ions present in the aloe

vera

now the raw materials that you require

to do the project is either you take a

fresh aloe vera leaf

cut it from the sides peel it off and

then remove that gel from it and use it

as your os and start off your analysis

salt analysis

in the end you will report you will be

reporting the mineral ions that are

present in your aloe vera solution that

you have and each of the mineral lines

has a use in your body or your skin

whatever it is

the

aloe vera that you use can also be a

commercial brand of aloe vera if you

want to use it i would advise that you

use a fresh

leaf of aloe vera from which you can

take out the extract please don't forget

to take pictures of your project while

you are in the process of

making the solution testing for the

precipitates all those images should be

there with your with yourself so that it

gives an authenticity to your project

that's one

second project could be coconut water

analysis this is again a type catin salt

analysis based project you can take

fresh coconut water which is transparent

and clear solution and you can start

your salt analysis with

lead group 1 group 2 you go to arsenic

and copper group 3 you go to iron and

aluminium

group 4 your manganese nickel cobalt

zinc barium strontium calcium and

magnesium

also you can do the flame test with your

solution add a little bit of hcl to it

and perform a flame test to check for

the presence of barium strontium and

calcium now when you write negative

tests that is also a project

so writing it that it does not have

copper is also an investigation

there are majorly negatives and a few

positives don't worry that itself is

important

so your

agenda for investigation project is you

are investigating and you are confident

about what you have done

results

that is also an achievement in

investigative project where you would

confidently say yes it does not have

copper ions

the third project idea is toothpaste

analysis

now when you do toothpaste analysis i

would advise please take the latest

brand of toothpaste colgate pepsident if

they have come up with a new gel

toothpaste a red gel blue gel whatever

it is you have those informations with

you and you can take a latest brand to

authenticate your project

the only problem with a toothpaste comes

is that if it's a white toothpaste you

do not get a clear os

so in that case what you need to do is

you need to prepare a sodium carbonate

extract

now what is that

take a small amount of toothpaste

add sodium carbonate to it a pinch or

two

add water to it

heat it

and let it settle down

so your anions would get settle down

because they will form your anions will

get dissolved because they will form

sodium sulfate sodium phosphate etc

filter it off now this original solution

that you have you can test for your

anions in this particular solution

coming for

because your tooth place majorly

contains carbonates aci levo vitae or

dissolved nail so when you acidify it it

requires a large amount of acidification

to become clear

solution

so see to it that you get a transparent

solution of a toothpaste if not

then you can use a gel based toothpaste

for your analysis which could be a

lighter colored gel so that you don't

face problems so if you have a white

colored toothpaste please make a clear

solution for it which will be by adding

excess of acid to neutralize all the

basic salts the carbonates present in it

now once you have a clear solution of

toothpaste you will again begin with

your anion analysis followed by the

cation analysis and your tables are to

be written in the project file and your

results in the end

you can also mention the basicity of a

toothpaste how is it helpful for your

non-cavity procedure and your dentist

advice this particular toothpaste if at

all you have that data that your dentist

has advised you sensody

or an oral b then you better analyze

that and find out what were the

components and how were these two

toothpastes sensodyne and oral be how

are these two toothpastes different from

the third so my advice is you take one

conventional toothpaste which could be

absorbent or colgate and other than that

take another medicinally proved

toothpaste or advised by a dentist and

you can compare the two also

so that becomes the third project idea

for analysis of

toothpaste moving on to the fourth idea

the fourth one is honey analysis now in

the market you would get honey by dabur

is what i know of you also have hamdard

honey that's up to you you can take any

one sample of honey

now is practical main there are two ways

of going about it in fact there are two

things that you can do one is your

presence of carbohydrate proteins fats

etc

there is already a video posted on my

channel where there are food tests how

they are to be done you can watch those

videos and do the same on to your honey

solution syrup honey

take two drops of honey add around four

to five ml of water make a solution and

that becomes your solution to test

proteins test career carbohydrates test

sugar benefit etc

that is one part

the second part is mineral iron testing

because honey does have certain minerals

which are good for your immunity system

so in that solution you will again start

off with an iron analysis and the

analysis now honey may clarity problem

it will be a clear original solution so

you don't need to bother much about how

to make a solution clear before you

start with the cation analysis so since

it is a clear solution you can directly

go about the analysis and get your

results for your presence of irons in

honey that could be your fourth project

idea moving on to the fifth project idea

now

the fifth idea is of

your breakfast cereals

your breakfast cereals are kellogg's

your cornflakes muesli

oats

and

dalia also is there so these are some of

your breakfast cereals which are in

demand these days

you can analyze the iron content present

in these breakfast cereals

you can take around and giving you rough

estimates rest is by practicals how you

would do it

two grams of your breakfast cereal here

add water to it

then add concentrated nitric acid to it

let's say 2 mlk curry

so that any ferrous if present converts

into ferric

that paste is difficult to filter so

what i would advise is use a sieve from

your kitchen first filteration can be

done via the sieve

but it will take time

if it is filterable through filter paper

awesome that would be the best

after filtering please see to it that

you add around 10 to 15 ml of water to

remove all the solutions sticking to

your ppt so that all the iron ions from

your residue move into the filtrate

once you get that solution now assuming

that your breakfast cereals have iron

content in them so all the

solution that you get will have your

iron salts in it

up

after this you need to add

sodium hydroxide solution to it make it

basic so that all the ferric transforms

into ferric hydroxide reddish brown

color

by adding around 10 to 15 ml of any

watch

now egg bar ppt sara

then you take a pre-weighed filter paper

filter paper

use that filter paper and filter a

filter off all the reddish brown ppt of

ferric oxide ferric hydroxide from that

particular filter paper so filter paper

on top of it you will get your reddish

brown colored ppt let it dry and then

re-weigh it let's say the weight is 1.8

which means 0.8 is the weight of your

ferric hydroxide so you can perform this

experiment for different cereals

find out the weight of ferric hydroxide

in all of them the one which has but use

the same amount of breakfast cereal if

you are using two grams of

cornflakes then two grams of foods two

grams of musically two grams of dahlia

that is how it will go so that there is

a comparative study

use

make all of their solutions add nitric

acid

boil it off

cool it

filter it to get a solution to that

solution you will now add sodium

hydroxide make it basic to get a ppt of

reddish brown colored ferric hydroxide

this ppt will tell you how much was iron

in your breakfast cereal please do it do

filtration should be done in a

pre-weighed filter paper so that the

weighing of the ferric hydroxide is

easier once you get your ppt you will

report your answer let's say i would

write conflicts the amount of ferric

hydroxide precipitated is 1.8 minus 1

gives me 0.8 grams of ferric hydroxide

the same i will do i will do it for

galia i will do it for conflicts and

then there will be a comparative study

that you can report

now the basic advantage

we did

aloe vera analysis we did coconut water

analysis honey analysis and iron content

in

breakfast cereals yeah projects can be

done in biology also

you do it just once

but report it in two ways make two

practical files project files sorry one

for chemistry one for biology one would

be signed by your bio teacher the other

would be signed by a chemistry teacher

the gypnity projects are related to

food articles

you can add disease section or

nutrition section or deficiency section

to make it a biology product also so the

projects related to food articles which

we just did that is your coconut water

honey analysis aloe vera analysis

toothpaste can also go that will give

you about your dental requirements that

is up to you but definitely aloe vera

coconut and honey

and the iron contents in breakfast

cereals can definitely go into your

biology practical also to open a key

project and it can be represented in

both the subjects fine because the

teachers will be different the same

teacher will not come for your

chemistry external and biology external

so don't worry about it

you will have both the projects ready

that is the advantage

lastly you have one more idea which i

had to propose is alloy analysis

you can take old coins

or else you can use safety pin staple

pen

board pens all pins

clips

hair pins all those metal articles all

of them are alloys

and you can also use coins other serif

coins use curve it could be coin

analysis

but if you are using safety pins etc the

articles from home then in that case it

could be called as an alloy analysis

whatever is your alloy

cheese article

considerable amount

add

them to a beaker and then add aqua regia

now what is aquaria aqua area is

three parts of concentrated hcl and one

part of nitric acid kamathler

you can do it this way take four beakers

take four different articles which could

be four different coins for four

different articles like staple pins all

pins safety pins and hair clips

charomay you need to add aquarius so

that the

article gets dipped into aquarius

so make a sufficient amount of aquarius

let's say 30 ml of hcl concentrated and

10 ml of nitric acid like a mix

and leave it for a day

you will have to leave it for a day

next day when you come

with the help of pair of tongs

remove the article if at all it is there

pura dissolves

but if it is there remove it that is

your leftover article

is your solution now this is the

solution which you are going to use to

check your

cations present

it is only cation analysis this is

highly acidic and it will work as your

os the dough drops solution

add 1 ml of water now this is your os

and start doing confirmatory tests

directly for lead

zinc aluminium copper

etc to confirm the presence of metal

ions in it because a loyal formation is

a property of d block of elements so try

to do the conformatory tests for copper

iron

nickel cobalt you can even do aluminium

because aluminium does form alloys

because it's a lighter metal

and you can even try magnesium try all

of them but do the confirmatory tests

only to give you a project file where

you have analyzed your coins and you are

or else you have analyzed the alloys

available in the daily

life so i have ended today's video where

i have shared six project ideas all the

project ideas are related to your salt

analysis so these project ideas would

only be done by people who are good at

salt analysis but even if you are not

good at salt analysis salt and ancestor

you will have to prepare for the

anion and cation analysis so separately

viva kelly you don't need to prepare

investigators projects viva would be

inclusive in your salt analysis but in

that case you should be very well

prepared with your salt analysis driver

so that the same viva would work for

both

i'll be uploading my next video would

have more ideas on projects please do

share these videos with your friends who

have to do

biology as well as chemistry projects in

the boards

fine

so

wait for my next video where i'll be

uploading the next set of

projects which will not be related to

short analysis

fine stay happy stay blessed

do share

love you all bye
