Sulphide ore on roasting gives a gas X . X reacts with Cl ₂ in the presence of activated charcoal to give Y . Y is
Options
- ASO ₂ Cl ₂
- BS ₂ Cl ₂
- CSCl ₆
- DSOCl ₂
Correct answer
A. SO ₂ Cl ₂
Step-by-step solution
When sulphite ore is roasted it means that sulphide ore is being heated in the presence of excess of air to form a gas SO ₂ . From sulphide ore) S + O ₂ (X) SO ₂ e.g. 2 ZnS +3 O ₂ 2 ZnO +2 SO ₂ Thereafter, X reacts with Cl ₂ in the presence of activated charcoal to give Y
