Cl₂(aq) and I⁻(aq) undergo redox reaction, while Cl⁻(aq) and I₂(aq) are products.
Cl₂(aq) is the oxidising agent because it is reduced as the oxidation state (or oxidation number) of Cl decreases from 0 (in Cl₂) to -1 (in Cl⁻).
I⁻(aq) is the reducing agent because it is oxidised as the oxidation state (or oxidation number) of I increases from -1 (in I⁻) to 0 (in I₂).
The answer:
Oxidising agent = Cl₂(aq), Reducing Agent = I⁻(aq)
Cl₂(aq) is the oxidising agent because it is reduced as the oxidation state (or oxidation number) of Cl decreases from 0 (in Cl₂) to -1 (in Cl⁻).
I⁻(aq) is the reducing agent because it is oxidised as the oxidation state (or oxidation number) of I increases from -1 (in I⁻) to 0 (in I₂).
The answer:
Oxidising agent = Cl₂(aq), Reducing Agent = I⁻(aq)
