Other Equilibrium Part 3, Predicting precipitation, selective precipitation, amphoteric hydroxides

We continue our discussion of solubility, equilibrium and using the solubility product constant, Ksp. In this video we show how we can use the reaction quotient, Q, to determine whether a mixture of solutions will result in a precipitation reaction. We also use this to discuss selective precipitation of ions from solution (which is essentially a method of separating ions in solution), and briefly touch on amphoteric hydroxides which can, as their name implies, act as both acids or bases.
