Spelling note: sulphuric acid = sulfuric acid, sulphate = sulfate, aluminium = aluminum (US)

You must know four general word equations, all of which involve neutralisation (Foundation or Higher students) and higher students would be expected to write and interpret them as symbol equations too. (i) is also a redox reaction.

(i) metal + acid ==> a salt + hydrogen

(ii) basic oxide or hydroxide + acid ==> a salt + water

(iii) carbonate + acid ==> a salt + water + carbon dioxide

(iv) ammonia + acid ==> ammonium salt (note: no water formed, but ammonia (NH₃) is an alkaline gas and soluble in water and neutralised by acids to form ammonium salts (NH₄ ...)

The name of the salt depends on (i) the metal name, which becomes the first part of salt name, and (ii) the acid e.g. H₂SO₄ sulfuric acid makes a ... sulfate (...SO₄), HCl hydrochloric acid makes a ... chloride (...Cl), HNO₃ nitric acid makes a … nitrate (...NO₃) and CH₃COOH ethanoic acid makes an ethanoate (...OOCCH₃ or CH₃COO..).

'SOME' FORMULA HELP: for MO, M = Mg, Ca, Cu, Zn ;  for MOH, M = Na, K ; for M(OH)₂, M = Mg, Ca, Cu, Zn;

for MCO₃, M = Cu, Zn, Ca, Mg ; for M₂CO₃ M = Na, K  ; and Al₂O₃, Al(OH)₃, AlCl₃, Al₂(SO₄)₃, NH₃, NH₄

and for CH₃COOM where M = Na, K and (CH₃COO)₂M where M = Mg, Ca, Cu, Zn.
