MCQ
A solution of sulphur dioxide in water reacts with ${H_2}S$ precipitating sulphur. Here sulphur dioxide acts as
  • As oxidising agent
  • B
    A reducing agent
  • C
    An acid
  • D
    A catalyst

Answer

Correct option: A.
As oxidising agent
(a)When sulphur dioxide is react with ${H_2}S$ here $S{O_2}$ act as an oxidising agent and ${H_2}S$ act as reducing agent.
