10. Potassium oxalate is a monohydrate salt that forms colorless, odorless crystals. Oxalic acid is a diprotic acid with Ka1 = 5.4 x 10-2 and Ka2 = 5.3 x 10-5. (a) If 1.843 g potassium oxalate monohydrate is dissolved in enough water to make 100.0 mL of solution, what will be the pH of the solution? (b) What is the equilibrium concentration of the fully protonated oxalic acid? (c) Is this solution a buffer? Explain.
