Suppose a biochemist has 10 ml. of a 1.0 M solution of a compound with two ionizable groups at a pH of 8.40. She adds
10.0 ml of 1.0 M HC1, 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 =
