Question

PLEASE CHECK MY WORK FOR MEDAL: REDOX PROBLEM

Choose which of the following is the reducing agent in the reaction:
HNO3 + HI --> NO + I2 + H2O
Select One:
a. H2O
b. NO
c. HNO3
d. HI

N goes from + 5 to +3 like an oxidizing agent .
I goes from -1 to 0 like a reducing agent . Would that mean the answer to the problem would be D.)?

Answer 2

The answer would be C, HNO3 because its oxidation state goes from +5 to +2 which means it is losing electrons. Losing electrons is oxidation and the reducing agent is oxidized.

Answer 3
