Question

What colour changes are expected in the organic layer when a solution containing each of [Fe(ox)]3]^3- and [fe(h20)6]^3+ is mixed with potassium iodide solution?

Note a pale violet colour in the organic layer indicates a prescence of iodine.

Use the following table

Explanation / Answer

2[Fe(H2O)6]3+ + 4[Fe(C2O4)3]3- +6KI -------------> 3I2 + 6K + [Fe(H2O)6]2+ + [fe(C2O4)2]2- + C2O42-

E0total = 2*0.77+ 4* 0.02 - 3*0.54 = 0

at equilibrium, there is a production of I2 which gives pale violet colour to the organic layer.
