Question

What products are formed from the reaction of cl2(g) with i–(aq)? select one:

a. icl
b. icl2
c. icl3
d. i2 and cl–
e. i and cl2–?

Answer 1

i2 and cl- because the chlorine atoms displace the iodide ions

Answer 2

Answer: option d. I₂ and Cl⁻(aq)

Justification:

Since chlorine (Cl) is a stronger oxididizing agent than iodine (I), and I⁻ is a stronger reducing agent than Cl⁻, you can predict that the Cl₂ will accept electrons from I⁻:

- Cl₂ will be reduced (gain electrons), while

- I⁻ will be oxidized (lose electrons).

This is the oxidation-reduction reaction:

Cl₂ + 2e⁻ → 2Cl⁻

2I⁻ → I₂ + 2e⁻

-------------------------------

Cl₂ + 2I⁻ → 2Cl⁻ + I₂ .

The right side shows the products as per the option d.
