Question

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

Answer 1

Answer: The species oxidized is
`I^-`.

The species reduced is
`Hg^(2+)`

The oxidizing agent is
`Hg^(2+)`

The reducing agent is
`I^-`

Step-by-step 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.

`Hg^(2+)+2I^-\rightarrow Hg+I_2`

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 .
