Separation And Purification

Question 1

Distillation

Answer 1

Separating mixtures with different boiling points by heating it up until one evaporates. It is collected after it condenses in the Liebig condenser.

Question 2

Fractional distillation

Answer 2

5 columns going cold to hot
High bps drain first from bottom
lower bps condense and drain out later on (near top of column)

Question 3

3 rate of reaction ways?

Answer 3

Amount used/product formed ÷ time

Precipitation and colour change

change in mass (usually gas given off)
quick reading drop quick reaction

Question 4

Filtration?

Answer 4

insoluble solids from liquids

liquid drips solid stays

Question 5

Evap

Answer 5

solution in dish
heat solution
solvent evaps
crystals form

Question 6

Crystallisation

Answer 6

same as evap
