2.Why is concentrated sulphuric acid unsuitable as a drying agent for hydrogen sulphide gas?
- A.It absorbs H₂S without reacting, making it ineffective.
- B.It reacts with H₂S to produce sulphur and sulphur dioxide.
- C.It decomposes H₂S into hydrogen and sulphur at room temperature.
- D.It forms a stable complex with H₂S, preventing drying.
-
