Question:
Suppose that 4.25 g of an unknown weak acid, HA, is dissolved in water. Titration of the solution with 0.350 m NaOH(aq) required 52.0 mL to reach the stoichiometric point. After the addition of 26.0 mL, the pH of the solution was found to be 3.82.
(a) What is the molar mass of the acid?
(b) What is the value of pKa for the acid?
