Filraction

Question 1

What is filraction

Answer 1

A fitration separated an undissolved solid from a solution or liquid.

A solution pass through the filter paper is called filtrate.

The solid remaining on the fitter paper is called the residues

The solid is wasted with a suitable solvent to remove traces of solution

Question 2

What are the steps of crystallization

Answer 2

1. Gently heat the solution in a evaporating basin to concentrate it
2. Evaporate the solvent until saturated solution crystallization point is related. This is reached when a drop of solution from crystal when place on a cold title.
3. Leave the saturated solution to cool and form crystal
4. Filter off crystal and dry them between filter paper

Question 3

What is simple distillation

Answer 3

Simple distillation is used to separate a liquid from a solid. Distillation involved the process of boiling condensation. It works because the components to be separate have very different boiling points.

Question 4

What is Fractional distillation

Answer 4

Simple distillation is used to separate two or more liquid with different boiling points from each other.

Question 5

What is Paper chromatography

Answer 5

Paper chromatography is used to separate a mixture of different dissolved substance. This method is often used to separate the different pigment coloured compounds present in food colouring and inks.

Question 6

Separating funnel

Answer 6

A separating funnel is used to separate immiscible liquid that have different densities. immiscible are liquid that do not mix
