Kidney stones are composed of crystals of calcium oxalate, CaC2O4. The solubility of CaC2O4 is
6.7 x 10-5 g per 100 ml of solution. What is the pH of a saturated solution of calcium oxalate? (Molar masses of Ca, C and O are 40.0 g/mol, 12 g/mol, 16 g/mol respectively.)

I am doing a lab report involving limiting reactants and percent compostition. The reactans are calcium chloride dihydrate and potassium oxalate monohydrate, which yeilds calcium oxalate monohydrate. My question is which product should i choose as my varied amount when doing my experiment that will yeild the best results of calcium oxalate monohydrate?
