Question

Name the substance oxidized, reduced, oxidizing agent, reducing agent in the following:

Pb(a)+ 4H₂O(PbSO4)+4H₂0​

Answer 1

Answer:

Here is the ans hope it's helpful for you☺

Explanation:

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

Reduced: 2H2O

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

Note:

Any species that is oxidised acts as reducing agent.

Any species that is reduced acts as oxidising agent.
