Question

The diagram represents the preparation of sodium sulphate salt from dilute $H_{2}S{O}_4$ acid and sodium hydroxide. Sulphurous acid forms two types of salts on reaction with an alkali:

• A. $CaS{O}_4$
• B. $N{a}_{2}S{O}_4$
• C. $NaCl$
• D. $MgS{O}_4$

Answer 1

Answer: (A), (D)

The correct options are
A $CaS{O}_4$
D $MgS{O}_4$

Group, I elements are known as alkali

Sulphurous acid form two types of salts on reaction with alkali are $MgS{O}_4$ and $CaS{O}_4$.
