##### 6 ptsQuestion 10A buffered solution (or simply a 'buffer") is a solution that maintains a relatively constanIpH even when of strong acids or bases are mixed into the solution. Such a buffer often contains a mixture of weak acid (the ~protonated form of the acid, AH) and its conjugated base (the deprotonated form A-). The buffers pH is determined by the ratio of the concentrations of the deprotonated form to the protonated forms (or [A7 / 0) according to the Henderson _ Hasselbalch equa
