Question

The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction _____.
a)loses electrons and loses potential energy
b)gains electrons and gains potential
c)energy gains electrons and loses potential energy
d)loses electrons and gains potential energy

Answer 1

Answer : The correct option is a) Loses electrons and loses potential energy.

Explanation :

Reducing agent : In a redox reaction, it is oxidized by the loss of electrons and by the loses of potential energy. It is also called as electron donor.

Reducing agent reduces others by loss of electron and its oxidation state increases.

For example : Sodium is a reducing agent and itself oxidized as follows,

$Na\rightarrow Na^++e^-$

Therefore, the molecule that function as a reducing agent in a redox reaction is loses electrons and loses potential energy.

Answer 2

The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction A. Loses electrons and loses potential energy

A redox reaction simply refers to the chemical reaction where the oxidation states of the atoms are changed.

In redox reactions, there is a transfer of electrons between the chemical species that are undergoing oxidation. The reducing agent loses electrons and loses potential energy.
