Redox reaction in acidic solution

I need to separate these into half reactions, and indicate the changes in oxidation state, then give the overall equation.

First I put water into a test tube, then I added potassium permangate. Next I added sulfuric acid, and after mixing that together I also added potassium iodide.  

I understand how to balance redox equations when given an equation and the product, but I don't know how to go about writing the equations for this since I'm not sure what the products are. This should be easy, but I'm just not getting it. If someone could show me the equations, and how to get them I would be very happy.

thank you
