Question

What is the balanced chemical equation for the reaction between potassium permanganate (KMnO4) and hydrogen peroxide (H2O2) in acidic medium?

Answer 1

In acidic medium, potassium permanganate  KMnO4  reacts with hydrogen peroxide  H2O2  to form manganese dioxide  MnO2 , potassium ions  K+ , water  H2O , and oxygen gas  O2 . The balanced chemical equation for this reaction is:2 KMnO4 + 3 H2O2 + 4 H+  2 MnO2 + 2 K+ + 6 H2O + 3 O2
