Suppose a biochemist has 10 mL of a 1.0 M solution of a compound with two ionizable groups at a pH of 7.60. She adds 10.0 mL of 1.0 M HCI, which changes the pH to 3.40. The pK, value of one of the groups is pK, = 3.90 and it is known that pK₂ is between 7 and 10. What is the exact value of pK₂? PK₂= 7.1 Incorrect
