Acids Reacting With Metal Oxides:
- acid + metal oxide -> salt + water
- Metal oxides are usually bases so they react with acids.
- E.g. hydrochloric acid + copper oxide -> copper chloride + water
- 2HCl + CuO -> CuCl3 + H2O
- E.g. sulphuric acid + zinc oxide -> zinc sulphate + water
- H2SO4 + ZnO -> ZnSO4 + H2O
Acids Reacting With Metal Carbonates:
- acid + metal carbonate -> salt + water + carbon dioxide
- E.g. hydrochloric acid + sodium carbonate -> sodium chloride + water + carbon dioxide
- 2HCl + Na2CO3 -> 2NaCl + H2O + CO2
- E.g. sulphuric acid + calcium carbonate -> calcium sulphate + water + carbon dioxide
- H2SO4 + CaCO3 -> CaSO4 + H2O + CO2
