Electrolysis of Potassium Iodide

Electrolysis is one of the methods used to break molecules to their elements. For example we use electrolysis of water to make Hydrogen and Oxygen gasses. Also electrolysis of molten Sodium Chloride (or table salt) produces chlorine gas and Sodium metal. Electrolysis can also help us to learn more about chemicals, their elements and the strength of their ionic bounds.

In this project we will perform the electrolysis of potassium iodide solution to see the results!

Unlike hydrogen and oxygen, both iodine and potassium are solids, so they can not exit the solution like gases. So what will happen to the potassium and iodine produced in this process? What will be the product of electrolysis of Potassium Iodide?

 Project description:
Electrolysis of potassium iodide is an experiment that takes about one hour. Gathering the material needed for experiments however needs more time. In this experiment you will use a battery and two electrodes and a solution of potassium iodide. You will also find methods to positively identify the products of this electrolysis process.
