When sodium carbonate, Na2CO3 dissolves in water, it forms the sodium cation and the aqueous carbonate anion, CO32-(aq). When hydrochloric acid dissolves in water, it forms the aqueous proton, or hydrogen cation, H+(aq) and the chloride anion. In this reaction, carbonate reacts with the hydrogen cation to form water and carbon dioxide (g). The sodium cation and the chloride anion just sit there, as ‘spectator ions’ and don’t react. Write an unbalanced equation for this reaction using only the reactive ions as reactants. This is called the ‘net ionic equation’:
