Oxalic acid is a diprotic acid with a first dissociation constant Ka1 = 0.0537 and a second dissociation constant Ka2 = 5.42×10-5. Consider all the species in equilibrium with each other in a 0.45 M solution. Note that the first acid dissociation constant is pretty large. This acid is almost a strong acid. Part 1:
What is the concentration of undissociated oxalic acid in the 0.45 M oxalic acid solution?

Part 2:
What is the concentration of hydrogen oxalate?

Part 3:
What is the concentration of oxalate?

Part 4:
What is the concentration of hydronium?

Part 5:
What is the concentration of hydroxide?

Part 6:
What is the pH of the solution?
