Give typed solution A compound has two carboxyls and one aminium group. The pKas of the groups are 2.1, 4.5, and 9.1, respectively. A biochemist has 100 mL of a 0.10 M solution of this compound at a pH of 5.2. She adds 29 mL of 0.1 M NaOH. To the nearest hundredth of a unit, what will be the pH of the solution after addition of the NaOH? (Assume full stirring to reach a new equilibrium.) (ANSWER IS 8.25, BUT UNSURE HOW TO GET THERE)
