Cell Potential

Cell Potential. L.O.: Construct redox equations using half-equations or oxidation numbers. Describe how to make an electrochemical cell. An oxidation number is a measure of the number of electrons that an atom uses to bond with atoms of another element.

6.2 Redox Reactions Changes at the electrodes

6.2 Redox Reactions Changes at the electrodes. EXAM TIPS: You will be expected to write half equations for the reactions at the electrodes. In half equations, the number of electrons MUST balance the number of charges on the ion. Objectives: I will understand
