Dentify the species oxidized, the species reduced, the oxidizing agent and the reducing agent in the following electron transfer reaction. Hg2+ + 2I- Hg + I2 species oxidized species reduced

 The species oxidized is .

The species reduced is

The oxidizing agent is

The reducing agent is

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

On reactant side:

Oxidation state of mercury = +2

Oxidation state of iodine = -1

On product side:

Oxidation state of mercury = 0

Oxidation state of iodine = 0

The oxidation state of mercury reduces from +2 to 0, it is getting reduced. Thus, it is getting reduced and acts as oxidizing agent.

The oxidation state of iodine increases from -1 to 0. Thus, it is getting oxidized and acts as reducing agent .
