Chemistry

1.For the diprotic weak acid H2A, Ka1 = 2.5 × 10-6 and Ka2 = 7.5× 10-9. What is the pH of a 0.0400 M solution of H2A? What are theequilibrium concentrations of H2A and A2– in this solution?

2.HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClOacts as a weak base. What is the pH of a solution that is 0.026 Min NaClO at 25 °C?

3.NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Clacts as a weak acid. What is the pH of a solution that is 0.057 Min NH4Cl at 25 °C?
