Sulphurous acid forms two types of salts on reaction with an alkali.

Answer 1

Answer:

(a) Two types of salts are formed when a sulphuric acid reacts with NaOH because of sulphuric acid is dibasic.

NaOH + H2SO4 → NaHSO4 + H2O.

2NaOH + H2SO4 → Na2SO4 + 2H2O.

(b) When hydrogen bromide reacts with sulphuric acid the bromine gas is obtained which produce red-brown vapors
