Question

Is h2so4 an reducing agent??

Answer 1

it is always an oxidizing agent. In H2SO4 sulphur is in +6 oxidation state. To act a a reducing agent one should lose electrons i.e; the atom should go from lower positive oxidation state to higher positive oxidation state. As sulphur is already in it's maximum possible oxidation state in H2SO4, further loss of electrons is not possible. So it can't act as a reducing agent.

Answer 2

Yes,it is a reducing agent
