Redox question?

Question

for the question 'Iron(III) chloride solution is added to potassium iodide solution and a redox reaction occurs.' how do you know what the two reacting species will be? i would have though that Cl would be included because its very highly oxidative but the Iodide is oxodised instead. why?

but how do you work that out?

Answer 1

The ionic equation is
2Fe3+ +2 I - >>2 Fe2+ + I2

Cl- and K+ are spectator ions

Answer 2

Dr. A's response is correct. In the reaction, the iron was reduced and the iodine was oxidized.
