Experiment #10 & #11 The Synthesis of Cobalt Oxalate Hydrate The Synthesis of a Nitrite Complex February 5, 2012 Chemistry 1211L - 146 - Spring 2012 Procedure The Synthesis of Cobalt Oxalate Hydrate Place 100 ml of distilled water in a 250-ml (or 400-ml) beaker. Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely. Dissolve 2.34 g of cobalt chloride hexahydrate (CoCl2.6H2O) in 100 ml of water in an Erlenmeyer flask. While stirring the oxalic acid solution constantly, add the cobalt chloride solution drop by drop. Let the mixture cool in an ice bath. A precipitate will form slowly. After the precipitate has had a…show more content…
Theoretical yield: 0.900 g Actual yield: 0.500 g % yield: 55.6% For Synthesis of a Nitrite Complex Equation: SrCl2.6H2O + NiCl2.6H2O + 6 KNO2 -> K2SrNi(NO2)6 + 4 KCl + 12 H2O The limiting reagent were SrCl2.6H2O and NiCl2.6H2O. Theoretical yield: 1.25 g Actual yield: 0.500 g % yield:
