Sodium phosphate buffer range
Buffer solution - Wikipedia, the free encyclopedia

For alkaline buffers, a strong base such as sodium hydroxide may be added. The buffer range can be extended by adding other buffering agents. A mixture containing citric acid, monopotassium phosphate, boric acid, and diethyl barbituric.

It can be defined as follows. Buffer capacity, β, is a quantitative measure of the resistance of a buffer solution to pH change on addition of hydroxide ions.

One example of a buffer solution found in nature is blood. Many life forms thrive only in a relatively small pH range so they utilize a buffer solution to maintain a constant pH. A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa.
