Answer to Question #293635 in General Chemistry for naj

Question

I– +Mno4 to I2 + Mno2

Answer 1

4 H₂O + 6 (I)^- + 2 MnO₄^- → 3 I₂ + 2 MnO₂ + 8 OH^-

This is an oxidation-reduction (redox) reaction:

2 Mn^VII + 6 e^- → 2 Mn^IV

(reduction)

6 I^-I - 6 e^- → 6 I⁰

(oxidation)

MnO₄^- is an oxidizing agent, I^- is a reducing agent.
