Mixtures:

-easily seperate mixtures bc chemicals in not joined together

-seperate by physical processes: filtration, crystallisation, simple distillation, fractional distillation & chromatogrophy 

-eg salt & copper mix

-seperate by adding water

-salt dissolves copper doesn't

-filter salt through filter paper, copper remains as residue

-salt solution can crystillised into salt crystals 

-physical process (no…
