GCSE Chemistry, Year 10, Preparation of Salts page

Salts are prepared by reacting an acid with a metal or a base, such as a metal carbonate, hydroxide or oxide. The acid provides the non-metal ion for the salt, e.g. chloride or sulphate or nitrate ions. The metal or base provides the metal ion for the salt, e.g. sodium or copper. The method used to produce a particular salt depends on two factors -
