Ph of buffer solution calculation
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. WebpH = pKa + log10 ( [A–]/ [HA]) Where [A –] denotes the molar concentration of the conjugate base (of the acid) and [HA] denotes the molar concentration of the weak acid. Therefore, the Henderson-Hasselbalch equation can also be written as: An equation that could calculate the pH value of a given buffer solution was first derived by the ...
