Would Cl2 be reduced by I - ? Explain.

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
