Question

Mention the oxidising agent and reducing agent in the following. H2 S + HNO3 ⎯⎯→ NO + S + H2 O

Answer 1

Answer:

The oxidizing agent is the one getting reduced:

O2 + 2 e-     ------> 2O-2

The reducing agent is the one getting oxidized:

2Li -------->   2Li+   + 2e-

Explanation:

Answer 2

Answer:

Explanation:

An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction.

A reducing agent, or reductant, loses electrons and is oxidized in a chemical reaction.

H2S + HNO3 ------> NO + S + H2O

here hno3 is oxidising agent as is reduces itself from oxidation state +5 to +2 and  h2s is reducing agent as it oxidises itself from -2 to 0.
