Question

The reaction of $H_2 O_ 2$ with hydrogen sulphide is an example of ................ reaction.

• A. addition
• B. oxidation
• C. reduction
• D. acidic

Answer 1

Answer: (B)

oxidation

Answer 2

When $H_2O_2$ is reacted with hydrogen sulphide
$(H_2S)$, it form S and water. In this reaction H2S is
oxidised to sulphur. $H_2O_2$ act as oxidising agent.
$H_2O 2 + H_2S \longrightarrow S + 2 H_2O$
