Witryna30 sty 2024 · When it comes to buffer solution one of the most common equation is the Henderson-Hasselbalch approximation. An important point that must be made about this equation is it's useful only if stoichiometric or initial concentration can be substituted into the equation for equilibrium concentrations. Origin of the Henderson-Hasselbalch … WitrynaSince NaOH is a strong base, it will react with the weak acid in the buffer to form its conjugate base. Therefore, we need to calculate how much of the weak acid is present in the buffer solution: moles of C6H5NH2 = concentration × volume = 0.231 M × 1.00 L = 0.231 mol.
