By combining substances with pKa values differing by only two or fewer and adjusting the pH, a wide range of buffers is usually received. Citric acid is often a practical element of a buffer mixture mainly because it has 3 pKa values, separated by lower than two.
Buffer solutions are needed in a wide range of programs. In biology, They're essential for preserving the correct pH for proteins to work; If your pH moves beyond a slender assortment, the proteins stop Functioning and might crumble.

An aqueous solution of an equal concentration of acetic acid and sodium acetate contains a pH of 4.seventy four.
If the difference between successive pKa values is lower than about 3, There may be overlap among the pH range of existence on the species in equilibrium.
