Question

Would Cl2 be reduced by I- ? Explain.

Answer 1

Yes. Cl has a is more electronegative than the iodide ion and thus attracts electrons more strongly than the iodide ion.

This is mainly due to the fact that chlorine has only 3 shells, compared to iodides 4 shells. This means a greater electrostatic attraction force exists between the chlorine nucleus and the outer electron than iodide and its outer electrons. As a result the Chlorine will be reduced to Cl- and iodide will be oxidised to iodine, as it will have lost its electron to the chlorine. 

The equation is 
Cl2 + 2I-  --> 2Cl- + I2 

Answer 2

Answer:

Yes, and it would yield gaseous iodine and chloride ions.

Explanation:

Hello,

In this case, when gaseous iodine reacts with iodide ions, the reaction results:

$Cl_2+I^-\rightarrow I_2+Cl^-$

In such a way, by balancing the reaction we obtain:

$Cl_2+2I^-\rightarrow I_2+2Cl^-$

Therefore, gaseous chlorine would be reduced by iodide ions yielding gaseous iodine and chloride ions.

Best regards.
