Separating mixtures
-
Simple distillation
Separates liquid from a solid (or 2 miscible liquids with differing boiling points), liquid is evaporated and condensed in a condenser and collected in a separate container
Fractional distillation
Separates miscible liquids with similar boiling points, flask heated, vapours from liquids pass into fractionating column, higher proportion of substance w a lower boiling point passes into condenser first, there is a thermometer measuring boiling point of liquid distilling over
Evaporation
Separates soluble solids from liquid, evaporate solution away
Filtration
Separate insoluble solid from liquid, filter paper collects solid and liquid passes through
Paper chromatography
Separate several solids in the same solvent, dyes are placed at the bottom of the chromatography paper, which is then placed in a solvent such as water, moves the dyes up at different rates depending on their solubility, numbers of spots above starting point tells us how many solutes there were in the og sample
Separating funnel
Separate immiscible liquids, liquid of lower density is at top, turn tap until the liquid of higher density has all gone, repeat if necessary

Rates of reaction
Collision theory
-
-
Collision that provides reaction - successful collision, activation energy is the minimum amount of area the collision creates for a collision to be successful
