When a weak acid dissolves in water it doesn t completely ionize dissociate but goes to equilibrium At equilibrium the rate in the forward direction is equal to the rate in the reverse reaction thus the concentrations no longer change When the concentrations are constant the ratio of the concentrations are also constant and this is called the equilibrium constant For the weak acid HF dissolving in water the Keq is defined as HF H O F H 0 products reactants A HF B H O C F D H 0
