Balancing Redox Reactions in Acidic and Basic Conditions
We know that redox reactions are ones that involve electron transfer. Something is oxidized, and something else is reduced. But these reactions can be tricky to balance when surrounding water molecules are involved in the reaction. Let's...

What Are Half Equations
In this video, we will learn how to write half equations for simple redox reactions. A half-equation shows what happens at one of the electrodes during electrolysis, so we need to be able to complete and balance half-equations for these...

Practice Problem: Galvanic Cells and Reduction Potential
We've learned about electrochemistry and electrochemical cells, especially galvanic or voltaic cells. And we learned about standard reduction potentials associated with a variety of substances. Given some data, can you calculate the cell...
