D. Preparation of Amine Complexes of Cobalt (III) (25 points) The following data resulted from performing the procedures of the lab: For preparation of [Co(NH3), CIJCI, Weight of cobalt (II) chloride: Moles of cobalt II chloride: Weight of recovered product, filter paper and watch glass Weight of filter paper and watch glass Experimental yield of product. Theoretical yield of product Percent yield of product For preparation of [Co(NH3)6]Cl3 Weight of cobalt (II) chloride: Moles of cobalt II chloride: Weight of recovered product, filter paper and watch glass Weight of filter paper and watch glass Experimental yield of product Theoretical yield of product Percent yield of product 6.50g 66.687 g 61.628 g 4.02g 51.891g 47.706g

1. How would the percent yield be affected if you did not dry the product completely? Explain your answer. (5 points) 2. What was the purpose of the hydrogen peroxide used in the lab? (5 points) 3. What might have happened if the drying oven temperature was set to 215°C instead of 110 °C?. (5 points)
