Suppose a biochemist has 10 mL of a 1.0 M solution of a compound with two ionizable groups at a pH of 7.50. She adds 10.0 mL of 1.0 M HCl, which changes the pH to 3.80. The p?a value of one of the groups is p?1=4.10 and it is known that p?2 is between 7 and 10. What is the exact value of p?2? Enter your answer to two significant figures. p?2 = ??
