How to solve henderson hasselbalch equation

WebAccording to the Henderson-Hasselbalch approximation (Equation 7.1.20 ), the pH of a solution that contains both a weak acid and its conjugate base is pH = pKa + log([A −] / [HA]). A Inserting the given values into the equation, pH = … WebThe Henderson-Hasselbalch equation relates pKa and pH. However, it is only an approximation and should not be used for concentrated solutions or for extremely low pH acids or high pH bases. pH = pKa + log ( [conjugate base]/ [weak acid]) pH = pka + log ( [A-] / [HA]) pH is equal to the sum of the pKa value and the log of the conjugate base ...
