Filtration And Crystallisation

Question 1

Filtration

Answer 1

A separation technique that separates an insoluble solid from a liquid

Question 2

Crystallisation

Answer 2

Separates a soluble solid solute from a solution

Question 3

Solvent

Answer 3

The substance that it dissolves in

Question 4

Solute

Answer 4

The substance that dissolves

Question 5

Solution

Answer 5

Formed when one substance dissolves in another

Question 6

Soluble

Answer 6

A substance that is dissolvable

Question 7

Insoluble

Answer 7

A substance that cannot dissolve

Question 8

Filtrate

Answer 8

The liquid that has passed through the filter

Question 9

Residue

Answer 9

The remaining of something

Question 10

Simple Distillation

Answer 10

Separates a liquid (the solvent) from the solution it is part of

Question 11

What are the three steps of Distillation?

Answer 11

1. Evaporation
2. Cooling
3. Condensation

Question 12

Chromatography

Answer 12

A technique used so separate mixtures of soluble substances

Question 13

Chromatography relies on different phases:

Answer 13

1. A stationary phase that does not move (solvent)
2. A mobile phase that does move(solute)

Question 14

Rf values

Answer 14

Distance of component/distance of solvent

Question 15

Thin-layer chromatography

Answer 15

The same technique as paper chromatography except the process continues with a thin sheet of glass or plastic layer of silicon or aluminium powder

Question 16

Fractional distillation

Answer 16

Separates liquids from a mixture depending on their boiling points

Question 17

RFM

Answer 17

Atomic mass x number of atoms in the pure substance added together

Question 18

Formulation

Answer 18

Mixtures that have been prepared using a specific formula, precise amounts of different components
