hai oke
halo halo anak-anak eh
Hai ketemu lagi dengan saya kali ini
kita akan membuat
yo yo Bagaimana cara keras yang benar
seperti yang sudah kalian pelajari
sebelumnya dijelaskan bahwa analisis
volumetri itu sebenarnya berhubungan
dengan proses keras ini nah bagaimana
cara posisi keras yang benar kita akan
sama-sama mempraktekkan untuk kedepan
Nanti kalian akan terapkan pada
penetapan penetapan sesuai dengan
kebutuhan nah
Hai tapi sebelum kita mulai
Hai stratifikasi pastikan dulu bahwa PD
yang kalian gunakan saat jelek itu sudah
lengkap Contohnya seperti yang saya
gunakan ada bogel pakai kacamata
pelindung
kemudian ada masker jas lab dan sebagai
Tomohon Kalian juga harus menyiapkan
kain lap tapi ini
Hai pakai sudah membuang waktu langsung
saja kita masuk pada proses filtrasi nah
tentunya sebelum memulai atraksi ada
beberapa hal penting yang perlu kalian
siapkan contohnya
kau berat yang akan Tersisih oleh
citraan kemudian Erlenmeyer yang akan
terisi oleh Citra Nah untuk iterasi kali
ini saya mengambil sampel atau contoh
yaitu titrasi netralisasi kasih Kekasih
naturalisasi itu prinsipnya adalah
penetralan asam dan basa untuk adalah
seperti yang kau
Hai bisa kalian lihat
Hai HCL
Hai dan basah yang akan saya gunakan
adalah enoha serta jangan lupa
indikator-indikator yang juga kena lain
di KTP atau fenoftalein
Hai nah
Hai jika sudah disiapkan titran Fitrah
dan indikatornya selanjutnya kita yang
pertama akan mengisi dulu burack dengan
sitrat
Hai nah sebelum udah diisi dengan Fitra
pastikan bahwa bulet sudah dua kali di
jelas
Hai penjelasan yang pertama menggunakan
aquadest dan pembilasan kedua
menggunakan pereaksi atau Citra yang
akan digunakan Nah untuk oval ini Anggap
saja kita sudah dua kali membilas
Hai nah kali ini kita akan langsung saja
kau mengisi surat dengan citra-citra
yang kita gunakan adalah haskell
Hai oleskan naaah mulut Buret
Hai diameternya kecil makan terbantu
atau dibantu harus dibantu dengan
10 kaleng nah seperti ini Curug harus
dikasih kertas mengganjal di bagian
sampingnya agar larutan dapat turun
Hai ke bawah
hai eh kok iya lupa jangan lupa kerjanya
hamsi tutup dulu
Halo Ajeng Saat kita membuang sitrat
larutannya tidak langsung muncul keluar
lagi dari Buret hatimu
+ packing
hai hai
hai hai
Hai nah
hai satu hal yang penting sebelum kalian
mulai trasi pastikan bahwa bagian bawah
burack itu gelembungnya sudah
dihilangkan nah seperti yang kalian
lihat di video ternyata dalam punya
masih ada Oleh sebab itu wajib untuk
kita hilangkan dulu beruntungnya seperti
ini
hai hai
hai hai
hai hai
hai hai
hai hai
Hai dibuka perannya perlahan-lahan
Hai nah jika sudah
Hai semuanya kembali ditutup sekalian
lihat leluhurnya sudah hilang
Hai Nah setelah gelembung dipastikan
hilang dulu baru kemudian pagar misi
lagi
Oh bulet dengan pikiran sampai
Hai sesuai dengan kejutan-kejutan
hai hai
hai hai
Hai nah ini sudah
Ya udah sudah terisi
Hai sampai ah larutannya atau titran
berada sedikit di atas kalah
Hai Nah setelah sudah
Hai penyiapan kitrans
Hai kembalikan murah pedas tapi
yang selanjutnya adalah ke preparasi
ciprat
Hai mati terus yang tadinya
aku masih di dalam labu ukur akan kita
pindahkan
hai hai
Hai ikan indahan
hai larutkan
Hai dari lagu kene ya untuk selanjutnya
diproses sebagai kita itu menggunakan
pipet volum sekalian lihat bertemu 10
milik jadi larutan yang akan kita
pindahkan akan sejumlah 10 milik
Hai jangan lupa prinsip-prinsip
pencegahan larutan yang sudah kalian
Hai lihat pada video sebelumnya
hai hai
hai hai
hai hai
hai hai
Hai pipet sampai terlalu tanya diatas
Hai tanda Tera kemudian
Hai jangan lupa untuk menyikat dulu
hai hai
hai hai
Hai jangan lupa untuk menyikat
Hai Nah setelah menikah
hai impitkan
di tengah sudah konsumtif lalu kemudian
kalian singgahi terlukanya keene ya
dengan posisi
Hai pipet volum dan RW yang membentuk
sudut 45° terkini
hai hai
hai hai
hai hai
Hai nah
Hai Citra nya sudah siap tinggal kita
encerkan Nah pengenceran itu bisa 50 ml
100 mili tergantung dengan kebutuhan
pemutaran Nah kalau kali ini kita akan
mengucapkan sebanyak kurang lebih
100.000
hai hai
Hai nah
Hai inilah fungsi Skywave
Hai Jadi jika ada yang
Hai teteh atau sumpah diatas meja kaki
itu maka air laut hajat wajib digunakan
seperti ini lanjut
[Musik]
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
hai hai
Hai Nah sudah cukup
Hai jangan lupa untuk meja selama proses
praktikum pastikan untuk tetap bersih
dan
MP3 ngajar
Hai melalukan yang sempat nangis ketika
demikian
Hai ini di terang sitrat oke citra-citra
yang akan kita analisis sudah siap di
leher
Hai setelah keras ya kita balik lagi ke
Hai sebelum pernikahan kita wajib untuk
memperkenalkan
kietrans
Hai pada skala 0
di situ nah
Hai jangan lupa Sebelum mengenalkan
makanan
Ayo kita wajib untuk menyeka
Hai banyak bagian atas kuret
Hai agar titik-titik larutan yang ada di
dinding urap
Hai tidak turun ke bawah dan mengganggu
proses titrasi
Hai atau mengganggu hasil diperas
Ya udah sedemikian
hai hai
Ayo kita from mrlokal
[Tepuk tangan]
Hai pastikan bahwa posisi mata
Hai harus sejajar dengan
hai hai
Hai cac3 sekolahnya sudah
Hai maka Citraland sudah siap untuk
digunakan
hai hai
hai hai
Hai sitrat sebelum disekitar
kita harus nambahin dulu indikator
seperti yang kalian lihat ini indikator
hai hai
hai hai
hai hai
Hai beberapa tetes indikator yang harus
ditambahkan itu tergantung oleh
kebutuhan
Hai seperti yang lagi penambahan
indikator Agan lebihin sampai warna
merahnya terlihat baru kemudian kita
kita
Hai dengan HCL yang berperan sebagai
titran nah
Hai pernah Kalian nonton digital
sebelumnya
hai hai
di bagian
Hai elne ya dibagian atasnya itu
dipegang oleh tangan
Hai tanam sedangkan krambu rap digenggam
oleh tangan kiri seperti yang kalian
lihat
Hai Erlin Mayer diputar-putar
Hai atau digoyang-goyang
Hai selama titrasi berlangsung
Hai tangan kiri memutar kran
Hai sehingga terkesan transferin ke
Erlenmeyer dan bereaksi dengan Citeureup
hai hai
Hai Nah untuk titrasi kali ini dia yang
kita harapkan adalah warna merah muda 11
hai hai
