Redox Reactions
In this video Paul Andersen explains how redox reactions are driven by the movement of electrons from the substance that is oxidized to the substance that is reduced. Oxidation is the loss of electrons and reduction is the gaining of...

Stoichiometry
In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used to...

Why Antidepressants Make You Feel Worse - At First
This problem of antidepressants making you feel worse can happen when we use it for anxiety or depression. With depression, you can feel even more depressed after you take it, but if you keep taking it, that effect wears off. The problem...

Practice Problem: Titration Calculations
Titration is a way to do stoichiometry with acids and bases. The equivalence point tells us something about the moles of acid and base that are present in solution at that moment. And if we know one of those values, we can know the...
