The pH of the solution does not decrease appreciably (it falls 3 in proportion to the change in ratio of salt to acid in solution). When an alkali (NaOH) is added: CH3COOH+Na+ +OH- ~CH3COO- +Na+ +H 2 0 The strong alkali, NaOH, dissociates completely into its constituent ions Na+ and OH-. OH- could have increased the pH, but in the buffer solution they react with CH 3COOH to give rise to water and acetate ions. The pH does not increase appreciably (it increases only in proportion to the change in the ratio of acid to salt in the solution).

Its imidazole is half ionized at that pH. We have already considered the importance of pK" for the buffering action of solutions. Because it has a pK" near to the blood pH. histidine possesses a significant buffering action in blood. Haemoglobin. the oxygen carrying protein of erythrocytes is a unique protein in that it contains a large number of histidine subunits in its structure. These histidine residues impart considerable buffering power to haemoglobin near pH 7. which is important to the role of red blood cells in the transport of oxygen and carbon dioxide by the blood.

PK··· ··ii,PK . 4? Properties of Amino Acids are pH-Dependent All the properties of amino acids which depend upon their ionization would naturally be affected Ly the prevailing pH . We can cite the example of solubility of amino acids. Amino acids are least soluble at their isoionic pHs. They are much more soluble at pHs lower and higher than their isoionic pHs. Thus. at a given pH different amino acids will have different solubilities depending upon how far removed is the pH of the solution from their own isoionic pOints.
