na2so3 and nahco3 may be distinguished by treating their

$$N{a_2}S{O_3}$$ and $$NaHC{O_3}$$ may be distinguished by treating their aqueous solution with :

A. $$MgO$$

B. $$MgS{O_4}$$

C. $${\text{litmus solution}}{\text{.}}$$

D. $$dil.\,{\text{acid}}$$

Answer : $$MgS{O_4}$$

Solution :
$$2MgS{O_4} + 2\,N{a_2}C{O_3} + {H_2}O \to $$ $$MgC{O_3}.Mg{\left( {OH} \right)_2} + 2N{a_2}S{O_4} + C{O_2}$$
$${\text{Basic magnesium carbonate}}$$
