Vedclass · Answer

(A) In an alkaline medium,$Na_2CO_3$ reacts with $SO_2$ to form $Na_2SO_3$ (sodium sulphite).The chemical reaction is as follows:$Na_2CO_3 + SO_2 \rightarrow Na_2SO_3 + CO_2$When $SO_2$ reacts with caustic alkalies or carbonates in an alkaline medium,it forms sulphites $(Na_2SO_3)$. In an acidic medium,it would form bisulphites $(NaHSO_3)$.

$Na_2CO_3$ reacts with $SO_2$ in an alkaline medium to form:
