reducing agent is substance which get oxidized itself by giving electrons :)
getting sleep by pumpkin love u hope you will solve it :)

anonymous · Answer

I believe its Mn02- because it gives electrons right? Thanks @chmvijay  have a nice nap! lol

Careful: in such a question, the reducing agent must be understood as one of the reactants, not one of the products.

Mn04- because it gives electrons? I believe i meant to say 4 not 2 for my first answer.

vincent-lyon.fr · Answer

No, because $MnO_4^-$ gains electrons by:

$MnO_4^- + 4H^+ + 3e^- \rightarrow MnO_2 + 2H_2O$
