5fe2+ + mno4- + 8h+ yields 5fe3+ + mn2+ + 4h2o in the equation above, a: h+ ions are reduced b: fe2+ ions are oxidized c: h+ is the oxidizing agent d: mno4- is the reducing agent

Option (D) is the correct answer.

Explanation:

A reducing agent is defined as an element or compound which accepts electron(s) and its oxidation number reduces.

For example,

Here, oxidation state of changes to , that is, it is oxidizing.

Whereas oxidation state of changes from , that is, changes from +7 to +2.

This means is the reducing agent.
