Precipitation Reactions: Crash Course Chemistry
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this...

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...

Extraction Using Heat
In this video, we will look at the chemistry behind the production of iron from iron ore. In early Earth history, iron, like all other metals, would have been found as an element in the crust of the planet. Later when plants evolved that...

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...
