Describe why buffering is needed
WebBuffer, as we have defined, is a mixture of a conjugate acid-base pair that can resist changes in pH when small volumes of strong acids or bases are added. When a strong base is added, the acid present in the buffer neutralizes the hydroxide ions (OH ^\text {-} - ). WebApr 21, 2016 · Why does a buffer work best at the $\mathrm{pH}$ closest to its $\mathrm{p}K_\mathrm{a}$? ... You need the weak base to react with added acid, and the weak acid to react with added base to stabilize the pH. When the pH is very different from the pKa, one of those two species will be at very very low concentration (there is an …

WebIt is a buffer because it contains both the weak acid and its salt. Hence, it acts to keep the hydronium ion concentration (and the pH) almost constant by the addition of either a small amount of a strong acid or a strong … WebMar 6, 2024 · Thus, the buffering region of the carbonic acid/ bicarbonate buffer is from about 5.37 to 7.37. It is maximally strong at a pH of 6.37. Now it starts to become apparent how the buffer works. HA can donate protons when extras are needed (such as when OH- is added to the solution by the addition of NaOH).
