6. Comment on the results. Specifically, is your analysis in error? Or , is any error you observe associated with the quality of the sample?
Conclusion This lab, as well as giving important laboratory experience, provided an in depth stoichiometry exercise. It showed the synthesis of a substance and how this substance could be tested for accuracy. Our results showed error, usually small but especially large in our yield of Ferric Oxalate Trihydrate, which was due to short crystallization time and loss of crystals during filtration and collection. Post Lab Questions: The Synthesis of Ferric Oxalate Trihydrate 1. What is the charge on the Iron Ion in the starting material, Ferrous Ammonium Sulfate Hexahydrate? Similarly, what is the charge on the Iron Ion in the product compound, Potassium Ferric Oxalate Trihydrate? How about for the reaction intermediate FeC 2 O 4 •2H 2 O?
2. In this laboratory you have used two different types of filtration. One is Gravity Filtration. The other is filtration using a Buchner Funnel. What is the principle difference in the purpose of these types of filtration?
3. Suppose I expect a Loss of 40%, how much Ferrous Ammonium Sulfate Hexahydrate must I start with in order to obtain 100g of Potassium Ferric Oxalate Trihydrate?
4. Ammonium Sulfate ((NH 4 ) 2 SO 4 ), Sulfuric Acid (H 2 SO 4 ) and Water (H 2 O) are all by- products of the first reaction in our synthesis. How much (mass) of each are produced when starting 5.00g of Ferrous Ammonium Sulfate Hexahydrate?
