The particular salt produced in any reaction between an acid and a base or alkali depends on: the acid used (hydrochloric acid produces chlorides, nitric acid produces nitrates, sulfuric acid produces sulfates) the positive ions in the base, alkali or carbonate. Predict products from given reactants. Use the formulae of common ions to deduce the formulae of salts. 2 Define the term neutralisation. Using common reactants, predict the products.
