2 KMnO4 + 2 NaOH + Na2SO3 → K2MnO4 + Na2MnO4 + H2O + Na2SO4 – Balanced equation

You are viewing the article: 2 KMnO4 + 2 NaOH + Na2SO3 → K2MnO4 + Na2MnO4 + H2O + Na2SO4 – Balanced equation at Traloitructuyen.com

Or you want a quick look:

This is an oxidation-reduction (redox) reaction:

2 Mn^VII + 2 e^- → 2 Mn^VI (reduction)

S^IV - 2 e^- → S^VI (oxidation)

KMnO₄ is an oxidizing agent, Na₂SO₃ is a reducing agent.
