WebThis is so called Henderson-Hasselbalch equation (or a buffer equation ). It can be used for pH calculation of a solution containing pair of acid and conjugate base - like HA/A -, HA - /A 2- or B + /BOH. For solutions of a weak bases sometimes it is more convenient to use equation in the form. 15.3. WebTo calculate the pH of a buffer solution, the Henderson-Hasselbach equation is commonly used. This equation can be derived quite simply from the behavior of weak acids (and bases) in solution, which is described by the kinetics of reversible reactions. This very equation is used in our Buffer pH Calculator.
WebWhen 1.0 mL of dil. HCl acid is added to 100 ml of a buffer solution of pH 4.0. The pH of the solution (1) Becomes 7 (2) Does not change (3) Becomes 2 (4) Becomes 10. Open in App. … 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.
