First write down the equilibrium expression This shows that when the acid dissociates, equal amounts of hydrogen ion and anion are produced. The equilibrium concentrations of these three components can be calculated in an ICE table (ICE standing for "initial, change, equilibrium").

A typical buffer solution can be made from ethanoic acid and sodium ethanoate. The ethanoic acid partially dissociates in solution: CH 3 COOH ( aq) ⇌ CH 3 COO - ( aq) + H + ( aq) The sodium ethanoate fully ionises in solution:
