chemical equilibrium
point at which both the forward and reverse reactions in a chemical equation have equal reaction rates. When this occurs the amounts of each substance in the chemical reaction will not change despite the fact that both reactions still proceed
Le Chatelier's principle
when a stress such as a change in concentration, pressure, or temperature is applied to an equilibrium the reaction will shift in a way that relieves the stress and restores equilibrium
acid ionization reaction
reaction in which an H+ ion separates from an acid molecule so that it can be donated in another reaction
acid ionization constant
equilibrium constant for an acid's ionization reaction
