WebTips for choosing an LC buffer Buffer Selection. The choice of the appropriate buffer for an application is governed by the buffer characteristics such as pK a, pH range, and UV cut-off. As a rule, buffers should be used for a pH within +/- 1 unit of their pK a value. Within this range, buffers resist any deliberate attempts of change in pH. WebOr a salt of weak acid and a weak base. Example: CH 3 COONH 4. Buffer Actions (a) Acidic Buffer: It is the mixture of CH 3 COOH and CH 3 COONa in aqueous solution. CH …

WebThe pH of the buffer is greater than 4.20. If HCl (aq) is added, the amount of benzoic acid would decrease. If NaOH is added, the amount of benzoate would increase. If HCl (aq) is added, the pH would increase by a small amount. A buffer is created by adding 10.0 mL of 0.250 M HNO 3 to 40.0 mL of a 0.500 M NH 3 solution.
