Both calcium chloride and sodium chloride are used to melt ice and snow on roads in the winter. A certain company was marketing a mixture of these two compounds for this purpose. A chemist, wanting to analyze the mixture, dissolved 2.463 g of it in water and precipitated calcium oxalate by adding sodium oxalate, Na 2 C 3 O 4 . The calcium oxalate was carefully filtered from the solution, dissolved in sulfuric acid, and titrated with 0 .1000 M KMnO 4 solution, the reaction that occurred was 6H + +5H 2 C 2 O 4 +2MnO 4 − → 10 CO 2 +2Mn 2+ +8H 2 O The titration required 21.62 mL of the KMnO 4 solution. (a) How many moles of C 2 O 4 2 − were present in the calcium oxalate precipitate' (b) How many grams of calcium chloride were in the original 2.463 g sample? (c) What was the percentage by mass of calcium chloride in the sample?
