Most biological systems must maintain a very narrow range of pH; therefore, buffers allow the biological solution to function correctly.

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...

Buffers are solutions designed to resist changes in pH from the addition of small amounts of acids or bases
Buffers are solutions designed to resist changes in pH from the addition of small amounts of acids or bases. Buffers are comprised of a solution of a weak acid with its conjugate base. When an outside base is added to the buffer, the weak acid in the buffer neutralizes the hydroxide ion of the base, thus retarding its ability to raise the solution's pH. When an outside acid is added to the buffer, the conjugate base of the buffer neutralizes...

Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 155 mL of a buffer that is 0.280 M in both benzoic acid (CH,COOH) and its conjugate base (CH,COO-). Calculate the maximum volume of 0.370 M HCl that can be added to the buffer before its buffering capacity is lost. 117.3
