    Your question relates to buffers, or solutions which resist changes in pH. Buffers are often used in biochemistry and typically are made with a weak acid (only partially dissociates in water) and a soluble salt containing the acid's conjugate base. There are literally hundreds of different buffer system; each buffer is most useful in the pH range at or close to a value known as the pKa. This is the negative log (base 10) of the Ka, which is the dissociation constant for the weak acid. In order to ...
