Consider the titration of a 40.0 mL of 0.189 M weak acid HA (Ka = 2.7 x 10⁻⁸) with 0.100 M LiOH. What is the pH of the solution at the equivalence point?

What is the pH at the equivalence point of a weak base-strong acid titration if 20.00 mL of NaOCl requires 28.30 mL of 0.50 M HCl? Ka = 3.0 × 10−8 for HOCl. (pH = −log[H3O+]; Kw = 1.0 × 10−14 at 25 °C; Kw = [H3O+] × [OH−]; Kw = Ka × Kb; pKa = −log[Ka]; Buffer: pH = pKa + log([base]/[acid])) 0.30 3.18 4.03 3.76

A 5.55-g sample of a weak acid with Ka = 1.3 * 10-4 is combined with 5.00 mL of 6.00 M NaOH, and the resulting solution is diluted to 750 mL. The measured pH of the solution is 4.25. What is the molar mass of the weak acid?
