Calculate the pH of the solution after the addition of each of the given amounts of 0.0697 M HNO, to a 80.0 mL solution of 0.0750 M aziridine. The pK, of aziridinium is 8.04. What is the pH of the solution after the addition of 0.00 mL HNO,? pH = What is the pH of the solution after the addition of 7.71 mL HNO,? pH = What is the pH of the solution after the addition of a volume of HNO, equal to half the equivalence point volume? pH = What is the pH of the solution after the addition of 82.6 mL HNO,? pH = What is the pH of the solution after the addition of a volume of HNO, equal to the equivalence point? pH = What is the pH of the solution after the addition of 90.8 mL HNO,? pH =
