bisulphite $\to$ Salt + Water
+ Sulphur dioxide

Solution

When acid reacts with sulphite $({S O}_{3}^{2 -})$ or bisulphite $({H S O}_{3}^{-})$ group they produce salt, water and sulphur dioxide gas.
When calcium sulphite reacts with hydrochloric acid, calcium chloride salt, water and sulphur dioxide gas are produced. The balanced chemical equation can be given as, ${C a S O}_{3} + H C l \to {C a C l}_{2} + H_{2} O + {S O}_{2}$
