1. 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 a 10 mL of 0.270 M hydroboric acid (HBr, strong acid) at 25°C. What is the pH of the solution after adding the 10 mL of HBr?
