Unformatted text preview: Lab Instructor: ______________________ Lab Section: ___________________________ 7 (b) A student synthesized 0.832 g of K 3 Fe(C 2 O 4 ) 3 ⋅ 3H 2 O by following the same instructions as given in this experiment. This 0.832 g sample reacted with exactly 14.01 mL of 0.138 M KMnO 4 according to the balanced equation above. Calculate the percent by weight of oxalate in the sample and compare it with the answer to part (a). 4. The experimental procedure directed you to cover the stored beaker to prevent complete evaporation of the water. Evaporation of all the water would have made it impossible to separate the desired product from “other salts, which would have remained in solution.” Assuming Fe(NH 4 ) 2 (SO 4 ) 2 ⋅ 6H 2 O is the limiting reactant, what other oxalate salt would most likely be in solution?...
