How do you predict redox reactions? like say they give you a solution of sodium iodide to react with an acidified solution of sodium permanganate?
both have sodium, and how do u find the products/how do you know which one is oxidized or reduced??

There are certain substances that have reached the limit of being oxidised or reduced, and so they can only go the other way.
Manganate(VII) - or permanganate - is as oxidised as it can be, so it can now only be reduced (ie act as an oxidising agent). Similarly, iodide ion has been reduced as much as it can be, so it can now only be oxidised - that is, act as a reducing agent.
A study of the topic of oxidation states and redox potentials should (eventually) enable you to judge which substances are good oxidising agents and which are good reducing agents without any trouble.
