WebThe average oxidation state of the sulfur atoms is therefore +2 1 / 2. STEP 3: Determine which atoms are oxidized and which are reduced. STEP 4: Divide the reaction into oxidation and reduction half-reactions and balance these half-reactions one at a time. This reaction can be arbitrarily divided into two half-reactions. WebMar 16, 2024 · The H 2 O 2 is also an oxidizing agent but in the reaction of KMnO 4 with the H 2 O 2 .The H 2 O 2 loses its electron and acts as a reducing agent. In an acidic medium, the MnO 4 − ions involve the addition of 5 electrons and the two peroxide ions give out two electrons. Complete step by step solution:
