The reaction is done with potassium manganate(VII) solution and hydrogen peroxide solution acidified with dilute sulphuric acid. How do I determine if this is true? Hydrogen Peroxide - H 2 O 2. It doesn't matter what the charge is as long as it is the same on both sides. It is an example of a redox reaction, with the following half reactions occurring (data from Vanýsek): Add appropriate coefficients (stoichiometric coefficients) in front of the chemical formulas to balance the number of atoms. Identify which reactants are being oxidized (the oxidation number increases when it reacts) and which are being reduced (the oxidation number goes down). Balancing result for chemical equations: h2o2 (hydrogen peroxide) h2so4 (sulfuric acid) kmno4 (potassium permanganate) = h2o (Water; Hydrogen oxide; Drinking water; Steam) mnso4 o2 (Oxygen; Oxygen molecule; Liquefied oxygen) k2so4 (potassium sulfate) . c) Combine these redox couples into two half-reactions: one for the oxidation, and one for the reduction (see: Divide the redox reaction into two half-reactions). a) Balance all other atoms except hydrogen and oxygen.
