How to solve henderson hasselbalch equation
WebMay 15, 2024 · The Henderson-Hasselbalch equation is: pH = pKa + log [conjugate base]/ [acid]. A modified equation is used when calculating the pH in a basic buffer solution. The modified equation is pH... WebMay 8, 2024 · There are three special cases where the Henderson-Hasselbalch approximation is easily interpreted without the need for calculations: [base] = [acid]: Under these conditions, \dfrac { [base]} { [acid]} = 1 \nonumber in Equation \ref {Eq9}. Because \log 1 = 0, pH = pK_a \nonumber regardless of the actual concentrations of the acid and base.
