9. Further examples of word and symbol equations for salt preparations

i.e. reactions of oxides, hydroxides or carbonates with acids

where it says similar, you can just change the metal name/symbol

These reactions apply to the salt making methods (a) & (b) described in section 6.

and also a word/symbol equation worksheet questions with answers


1a. copper(II) carbonate + sulphuric acid ==> copper(II) sulphate + water + carbon dioxide
