WebbMolarity of the acid = (1000 × 0.000997)/10. [HA] original = 0.0997M. Note: 10ml acid was diluted by adding 10ml water before titration. Therefore, the concentration of the acid used to calculate Ka is half the original concentration. Therefore, [HA] diluted = 0.0997/2. WebbSo when we plug in that concentration, we get the pH is equal to negative log of 1.8 times 10 to the negative fifth which is equal to 4.74. So if you react a weak acid with a strong …

WebbHowever, for weak acids, a quadratic equation must be solved, and for weak bases, a cubic equation is required. In general, a set of non-linear simultaneous equations must be solved.
