When H2S gas is passed through an acidified solution of CuSO4, a black precipitate is obtained.


Ans.

  1. Hydrogen sulphide reacts with an acidified solution of CuSO4­, to form a black insoluble copper sulphide.
  2. Hence, when H2S gas is passed through an acidified solution of CuSO4, a black precipitate is obtained.
