Separating Mixtues

Question 1

Concentration

Answer 1

mass of substance in particular volume

Question 2

Volatile

Answer 2

liquids that can evaporate quickly

Question 3

limescale

Answer 3

a hard solid residue formed when hard water is heated or boiled

Question 4

filtrate

Answer 4

solution that passes through filter paper during filtration

Question 5

simple distillation definition

Answer 5

solvent from solution

Question 6

distillate

Answer 6

liquid which evaporates then condenses and emerges from condenser

Question 7

evaporation

Answer 7

solids from solution
e.g. salt from saltwater

Question 8

separating funnel

Answer 8

separating liquids that don’t mix

Question 9

residue

Answer 9

solid left in filter paper after filtration

Question 10

fitration

Answer 10

insoluble solids from liquids

Question 11

distillation method

Answer 11

heat solution so it evaporates, turning into a vapour
vapour rises and enters condenser
condenser is cold, water vapour condenses and drips out of condenser into conical flask as distillate

Question 12

chromatography method

Answer 12

cut section of filter paper as a wick
drop wick into water, liquid drawn up through ink
colour begins to separate on its own
travel up to solvent front
