    soluble salts:
    1) metal + acid --> salt + hydrogen
    2) acid + base --> salt + water
    3) acid + alkali --> salt + water
    4) crystallisation:
    - metal or base added to acid until all of acid has reacted
    - mixture filtered to remove excess solid
    - left with solution of salt
    - water is evaporated from solution so it crystallises and a solid salt is made

    insoluble salts:
    1) combine 2 solutions containing 2 different soluble salts which forms an insoluble precipitate
    It is used for treating water for drinking or in treating effluent.

    I think that's all we need to know for C2 tomorrow
