The balanced reaction of oxalic acid with potassium dichromate in an acidic solution is: 3H2C2O4(aq) + K2Cr2O7(aq) + 5H2SO4(aq) --> 2KHSO4(aq) Cr2(SO4)3(aq) 6CO2(g) 7H2O(I) In an experiment, 2.7000g of H2C2O4, 2.8500g of K2Cr2O7, and 3.5000g of H2SO4 are combined and 1.7500g of KHSO4 and 2.500g of Cr2(SO4)3 are recovered. 1) Find the limiting reagent. 2) Find the theoretical yield of both KHSO4 and Cr2(SO4)3 in grams. 3) Find the amounts of excess reagent left over in grams. 4) Find the Percent Yield of both KHSO4 and Cr2(SO4)3.
