Carbonates contain the CO32- ion.acid + carbonate → salt + water + carbon dioxide.CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)Hydrogencarbonates are compounds containing the hydrogencarbonate ion HCO3-These reactions are neutralisation reactions but are not classified as redox reactions.Acids can be used to test for the presence of carbonates and hydrogencarbonates.
