Consider the following reaction:

I2O5 (s) + 5 CO (g) → I2 (s) + 5 CO2 (g)

Which of the following correctly characterizes this reaction?

The oxidation number of iodine in the reactants is + 5.

CO is oxidized.

I2O5 is the oxidizing agent.

The three statements are true

Explanation:

For the reaction:

I₂O₅ (s) + 5CO (g) → I₂ (s) + 5CO₂ (g)

State oxidation of iodine in I₂O₅ is:

5 O²⁻ = 10⁻

As you have 2 I and the molecule has no charge, oxidation state of I is + 5.

The carbon in CO has an oxidation state of + 2 and in CO₂ is + 4. That means the carbon is oxidized

An oxidizing agent is a substance that produce the oxidation of the agent that reacts with this one. CO is oxidized because of I₂O₅ is producing its oxidation being the oxidizing agent

Thus, the three statements are true.
