Question

Ag2SO4 + 2H2O +SO.
In the reaction
2Ag + 2H2SO4
Sulphuric acid acts as:
(a) Oxidising agent
(c) Catalyst
(b) Reducing ag
(d) Acid as well
O​

Answer 1

Oxidizing agent.

This is because, in the reaction,

2Ag + 2H₂SO₄ ⇒ Ag₂SO₄ + 2H₂O + SO

Ag's oxidation state changes from 0 to +2, i.e. loss of electrons, i.e. increase in oxidation number and hence gets oxidized.

Oxidizing agent oxidizes a substance while undergoing reduction.
