Question

13. In the reaction PbS (s) + 4H2O2(aq) -- PbSO4(s) + 4H20 (1), which is oxidizing agent and
which is reducing agent? (3)
​

Answer 1

Answer: oxidising agent is Hydrogen peroxide (H2O2 )

Reducing agent is PbS

Explanation:

As Hydrogen peroxide get reduced to water hence oxidise PbS to PbSO4

Hence act as oxidising agent
