Precipitation Reactions: Crash Course Chemistry #9

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other and form an insoluble compound, they suddenly fall out of the solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.
