Buffer Calculations for Polyprotic Acids

Buffer Calculations for Polyprotic Acids A polyprotic acid can form buffer solutions in presence of its conjugate base. For example, phosphoric acid can form a buffer when combined with its conjugate base (dihydrogen phosphate). H 3 PO 4 D H + + H 2 PO 4 - k a1 = 1.1 x 10 -2

Buffers

Buffers. A Buffer in Action. Definition of a Buffer. A buffer solution is one which resists changes in pH when small quantities of an acid or a base are added to it. The most important way that the pH of the blood is kept relatively constant is by buffers dissolved in the blood.
