Question

in an oxidation - reduction reaction, how is the reducing agent changed? it gains electrons and gains potential energy. it gains electrons and loses potential energy. it loses electrons and loses potential energy. it loses electrons and gains potential energy.

Explanation:

In an oxidation - reduction reaction, the reducing agent is oxidized. Oxidation involves the loss of electrons. When a substance loses electrons, it loses potential energy (as electrons in higher - energy orbitals are lost).

Answer:

It loses electrons and loses potential energy.
