Batteries power much of our lives (literally). In this tutorial, we'll use our knowledge of oxidation and reduction to understand how Galvanic/Voltaic cells actually work.
What happens when you add zinc to a solution of copper sulfate? Identifying the half reactions to see what got oxidized and reduced.
How to use a redox reaction to construct a galvanic/voltaic cell to produce a flow of current.. Shows the flow of electrons and ions, and explains the role of the salt bridge.
Identifying the anode and cathode in a galvanic cell, and calculating the voltage using standard electrode potentials.
How to describe cell using shorthand notation.
Balancing the redox reaction (in acid) that occurs in a lead storage battery.
Balancing the redox reaction (in base) that occurs in a nickel-cadmium battery.
