How do you calculate the pH of a buffer solution? Socratic

WebAlkaline buffer solutions are commonly made from a weak base and one of its salts. A frequently used example is a mixture of ammonia solution and ammonium chloride solution. If these were mixed in equal molar proportions, the solution would have a pH of 9.25. Again, it doesn't matter what concentrations you choose as long as they are the same. WebOne way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. When [HA] = [A⁻], the solution pH is equal to the pKₐ of the acid. Created by Jay. WebJan 30, 2024 · pH = pka+log ( [A - ]/ [HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid.
