Learning+Objectives

Here are the Learning objectives...   Are you ready? **Let's Go** ... Definition 1
 * 1) define oxidation and reduction (redox) in terms of oxygen/hydrogen gain/loss;
 * 2)  define //redox// in terms of electron transfer and changes in oxidation state
 * 3)  identify redox reactions in terms of oxygen/hydrogen, electron gain/loss and changes in oxidation state
 * 4)  describe the use of aqueous potassium iodide and acidified potassium dichromate(VI) in testing for oxidising agent and reducing agent from the resulting colour changes
