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
