3. A 0.270 M solution of sodium formate, used in several fabric dyeing and printing processes, is prepared by dissolving it in water. A 75.0-mL sample of this sodium solution is titrated with 0.270 M hydroboric acid (HBr, strong acid) at 25°C. What is the pH of the solution after 15 mL of HBr has been added beyond the equivalence point of the titration. Sodium formate is a basic salt, with the formula HCOONA, and the acid- ionization constant of its conjugate, formic acid (HCOOH), is 1.7 x10-4 at 25°C.
