Comment on the results. Specifically, is your analysis in error? Or , is any error you
observe associated with the quality of the sample?
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
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
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?
