WebApr 9, 2024 · pH = pKa + log [A−] [HA] where A− is the benzoate and HA is the benzoic acid. The ratio is then... 4.00 = 4.20+ log [A−] [HA] ⇒ [A−] [HA] = 104.00−4.20 = 0.6310 It makes sense; pH < pKa, so the solution is more acidic than if there were equal quantities of benzoate and benzoic acid. Hence, there is more weak acid than weak base.
WebApr 16, 2007 · Calculate the change in pH of a 0.400 M C6H5COOH solution when 100.0 ml of a 2.50 M KOH solution is added to 1.000 L of C6H5COOH. For C6H5COOH, Ka = 6.46 X 10^-5. Work Done So Far: We're to determine the change in pH, thus we'll need to find the original pH.
