What is a good reducing agent? A. A substance that is good at oxidizing another atom

B. A substance that is good at reducing another atom

C. A substance that is a good electron acceptor

D. A substance that is easily reduced in a reaction

B. A substance that is good at reducing another atom

Explanation:

Reducing agents:

Reducing agents reduced the other element are it self gets oxidized.  They have very low ionization energy and easily lose the electron.

Consider the following reactions.

4KI + 2CuCl₂  →   2CuI  + I₂  + 4KCl

the oxidation state of copper is changed from +2 to +1 so copper get reduced.  It means it gain one more electron.

CO + H₂O   →  CO₂ + H₂

the oxidation state of carbon is +2 on reactant  side and on product side it becomes  +4 so carbon get oxidized.  Carbon loses it two more electron and act as reducing agent.

Oxidizing agents:

Oxidizing agents oxidize the other elements and itself gets reduced.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.
