Answer 2

$\mathrm{PbS}+4 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{PbSO}_{4}+4 \mathrm{H}_{2} \mathrm{O}$

What is oxidation and reduction reaction?

• An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
• Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

What is the difference between oxidation and reduction?

• It loses electrons in a reaction in chemistry if a substance is oxidized.
• It gains electrons in a reaction if a substance is reduced.

• A reaction within which there is both oxidation and reduction is called a REDOX reaction.

According to the question:

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

Reduced: $\mathrm{H}_{2} \mathrm{O}_{2}$ 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.
