H2S + KMnO4 + H2SO4 = S + MnSO4 + K2SO4 + H2O | Chemical reaction and equation Hydrogen sulfide react with potassium permanganate and sulfuric acid 5H 2 S + 2KMnO 4 + 3H 2 SO 4 → 5S + 2MnSO 4 + K 2 SO 4 + 8H 2 O [ Check the balance KMnO4 or rather MnO4 - is the oxidising agent and H2S is the reducing agent. We can divide the equation into the oxidation and reduction half-equations. MnO4 - => Mn ++ , reduction half-equation (1a) H.. Answer and Explanation: The unbalanced reaction is completed as shown below. KMnO4 +H2SO4+H2S → MnSO4+K2SO4+H2O+S K M n O 4 + H 2 S O 4 + H 2 S → M n S O 4 + K 2 S O 4 + H 2 O + S In the above.. Hydrogen peroxide reacts with potassium permanganate and sulfuric acid (KMnO4 H2O2 H2SO4) The reaction is an electron exchanging reaction. The reactants in this reaction give and take a certain amount of electrons to make some product. Here, in this chemical reaction, the KMnO4 and H2O2 play the main role, as they exchange the electrons. On the other side, the sulfuric acid (H2SO4) just makes a suitable reaction environment. Since there is electron exchange takes place, we can.
