Quotient

In this part 9 of the solution equilibrium series we analyze the solubility product constant in light of being added to a solution of a common ion, plus we learn how to use the reaction quotient (Q) to predict whether or not a solution will form a precipitate.

Chemical Equilibrium Part 4 for Mr. Newton's AP Chemistry class. This video explains how to use the "Q" or the reaction quotient expression to take any starting condition and figure out which direction the reaction will proceed in to reach equilibrium by comparing it to the equilibrium constant expression
