An aqueous solution of gas ‘A’ gave the following data (reactions): It decolourised an acidified KMnO_(4) solution.

Aqueous solution of a salt (A) forms a dense white precipitate with BaCl_(2) solution . The precipitate dissolves in dilute HCl to produce a gas (B) which decolourises acidified KMnO_(4) solution . A and B respectively are :
