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.

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 1.842 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 will be the
equilibrium concentration of the fully protonated oxalic acid?

A student weighed out 1.0093g of copper sulfate pentahydrate and
2.4780g potassium oxalate monohydrate made them react and isolated
the product.
This is the provided balanced equation:
CuSO4*5H2O(aq)+2K2C2O4-H2O--->K2[Cu(C2O4)2]*2H2O(s)+K2SO4(aq)+5H2O
a) calculate the molar mass of copper sulfate pentahydrate,
potassium oxalate monohydrate.
b) calculate the moles of each reagent based on the mass weighed
out for each.
c) Determine which is the limiting reagent.
d) Calculate the molar mass of potassium dioxalatocuprate(II)
dihydrate.
