Answer #1

Oxidation involve increase in oxidation number and reduction involve decrease in oxidation number.

Oxidizing agent is one which itself get reduced and reducing agent is one which itself get oxidized.

HNO₃ + (%, o +3 +6 tut reduction ( 3+ + No, +40 t3 ts3 - +3 oxidation oxidation half reaction Reduction half reaction MNO2 -
