Which substance is the reducing agent in this reaction? 2KMnO4+3Na2SO3+H2O→2MnO2+3Na2SO4+2KOH
The reducing agent would be the substance that is oxidized in the reaction or the one who loses electrons. From the reaction given, it would be KMnO4 that is the reducing agent. It loses electrons From (MnO4)2- to MnO2. Hope this answers the question.
