Separating Mixtures – Filtration
Summary
TLDRThis video demonstrates how to separate a mixture of sand and water using a technique called filtration. First, sand is poured into a beaker of water to create the mixture. Then, a retort stand, glass funnel, filter paper, and another beaker are used for the filtration process. The filter paper traps the solid sand particles, while the water passes through, leaving the sand as the residue and the water as the filtrate. This clear explanation of filtration highlights how solids and liquids can be separated effectively.
Takeaways
- 🎶 The video features a demonstration with a dish of sand and a beaker of water.
- 🔄 The mixture is made by combining sand with water and stirring it together.
- 🧪 The method to separate a solid from a liquid in a mixture is called filtration.
- 🛠️ The tools used for filtration are a retort stand, glass funnel, filter paper, and a beaker.
- 📜 Filter paper has tiny fibers and small holes that allow liquids to pass through while trapping solids.
- 🚰 When the mixture is poured over the filter paper, the liquid passes through the holes, but the solid stays behind.
- 🧱 The sand remains as residue on the filter paper after filtration.
- 💧 The water that passes through the filter paper is called the filtrate.
- 🌊 The separated components are sand (solid) and water (liquid).

Q & A
What materials are used to create the mixture of sand and water?
-A dish of sand and a beaker of water are used to create the mixture.
What is the first step to make the mixture?
-The first step is to pour the sand into the beaker of water and stir it.
What technique is used to separate a mixture of a solid and a liquid?
-Filtration is the technique used to separate a mixture of a solid and a liquid.
What equipment is needed for the filtration process?
-A retort stand, glass funnel, filter paper, and a beaker are needed for the filtration process.
What is filter paper and how does it work?
-Filter paper is a special kind of paper made of tiny fibers pressed together with tiny holes in between. It allows liquid to pass through while trapping solid pieces.
What happens to the liquid and solid when the mixture is poured over the filter paper in a funnel?
-The liquid passes through the holes in the filter paper, while the solid pieces get trapped in the filter paper.
What is the term used for the solid matter that is held by the filter paper?
-The solid matter held by the filter paper is called the solid residue.
What do we call the liquid that passes through the filter paper and remains in the beaker?
-The liquid that passes through the filter paper and remains in the beaker is called the filtrate.
Can filtration be used to separate any mixture of solid and liquid?
-Filtration can be used to separate mixtures where the solid particles are larger than the holes in the filter paper.
Why is it important to use filter paper with tiny holes for the filtration process?
-It is important because the tiny holes allow the liquid to pass through while trapping the solid particles, effectively separating the mixture.
Outlines
🧪 Creating a Mixture of Sand and Water
The speaker demonstrates a simple experiment using sand and water. They begin by pouring sand into a beaker of water, stirring it to create a mixture. This sets up the experiment for separating the mixture back into its original components.
🔍 Introducing Filtration as a Separation Technique
The speaker explains how a mixture of a solid and a liquid can be separated using filtration. They introduce the necessary tools: a retort stand, a glass funnel, filter paper, and a beaker. Filter paper is highlighted as a key tool for separating solids from liquids due to its tiny fibers with small holes.
🧴 Demonstrating Filtration Process
A practical demonstration of filtration is shown. The mixture of sand and water is poured through filter paper. The liquid (water) passes through the paper, while the solid (sand) is trapped. This process successfully separates the mixture into its solid and liquid components.
🏖️ Residue and Filtrate Explained
After filtration, the speaker describes the outcomes. The sand, trapped by the filter paper, is called 'residue,' while the water, which passes through, is termed 'filtrate.' The experiment successfully demonstrates how to separate a mixture using filtration.

here we have a dish of sand and a beaker
of
water let's make a mixture by pouring
the sand into the beaker and giving it a
stir now we have a mixture of sand and
water how can we separate the mixture
back to its original
components when we have a mixture of a
solid and a liquid we can separate the
mixture using a technique called
filtration here we have a retort stand
glass funnel filter paper and a
beaker filter paper is a special kind of
paper that helps us separate the solids
from the liquids in a mixture it's made
of very tiny fibers pressed together
that have teeny tiny holes in between
them when you pour the mixture over the
filter paper in a funnel the liquid can
pass through the
holes but the solid pieces are too big
to fit through so they get trapped in
the filter paper let's see this in
action great the mixture has been
separated the solid matter the sand is
held by the filter paper we call this
The solid
residue the liquid in this case water
passed through the the filter paper
what's left in the beaker is just the
water which we call the
filtrate don't forget to
