Text Solution

Verified by Experts

The precipitate of second group sulphides in qualitative anlysis is carried out with hydrogen sulphide in the presence of hydrochloride acid but not in mitric acid.
Nitric acid is a strong oxidising agent and oxides `H_(2)S` into S, So it cannot be used in the reaction involving hydrogen sulphide
