Consider the titration of 40.0 mL of 0.171-M of KX with 0.141-M HCl. The pKa of HX = 10.89. Give all pH values to 0.01 pH units. a) What is the pH of the original solution before addition of any acid? pH = b) How many mL of acid are required to reach the equivalence point? VA = mL c) What is the pH at the equivalence point? pH = d) What is the pH of the solution after the addition of 24.7 mL of acid? pH = e) What is the pH of the solution after the addition of 58.2 mL of acid? pH =
