When the pH of the solution is equal to the pKa of the ionizing group, the solution is functioning at maximum buffering capacity (best buffer). An aqueous solution of a conjugate acid/base pair functions as a good. buffer when the ratio of the conjugate base to weak acid ranges from 1:9. to 9:1.
Definition A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it. Acidic buffer solutions An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts-often a sodium salt. A common example would be a mixture of ethanoic acid and sodium ethanoate in solution. In this case, if the solution contained equal molar concentrations of both the acid and the salt, it would have a pH of 4.76.
