Question

name the substance oxidized , reduced, oxidising agent and reducing agent in the following- Pb+4H2O----PbSO4+4H2O​

Answer 1

Explanation:

PbS+4H ²O²---PbSO4 + 4H20

Oxidised : PbS. The oxidation number of S increases from -2 to +6. Thus, S itself is oxidised and acts as reducing agent.

Reduced: H²O²

The oxidation number of O decreases from -1 to -2. Thus, O itself is reduced and acts as oxidising agent.
