What is the reducing agent in the following reaction 5Fe2+(aq) + MnO4-(aq) + 8H+(aq) → 5Fe3+(aq) + Mn2+(aq) + 4H2O(I)
A. MnO4-
B. Fe3+
C. Mn2+
D. Fe2+
E. H+

is the reducing agent

Explanation:

Oxidation reaction : When there is an increase in oxidation state number.

Reduction reaction : when there is a decrease in oxidation state number.

Fe has undergone oxidation, as its oxidation state is changing from+2 to +3.

Mn has undergone reduction, as its oxidation state is changing from +7 to +2.

The chemical agent which itself get oxidized and reduce others is called reducing agent.    is a reducing agent.

The chemical agent which itself get reduced and oxidize others is called oxidizing agent. is an oxidizing agent.
