🤓 Based on our data, we think this question is relevant for Professor Smeureanu's class at HUNTER.
For the diprotic weak acid H2A, Ka1 = 3.1 X 10-6 and Ka2 = 5.1 X 10-9. What is the pH of a 0.0500 M solution of H2A? What are the equilibrium concentrations of H2A and A2- in this solution?
pH = ?
H2A = ?
A2- = ?
