Copperas (crude ferrous sulfate) is purified by dissolving it in water and recrystallizing it in a crystallizer. First, copperas is dissolved in pure water to give a solution containing 28% FeSO4 (by weight). The solution is cooled to 10 0C to give out the crystals of FeSO47H2O crystals. The original copperas contains 96% FeSO47H2O (by weight). Find the quantity of copperas charged to the crystallizer. The solubility of FeSO4 at 10 0C is 20.51 g per 100 g water. Assume that the solubility of FeSO4 at 100C is unaffected by the impurities present in copperas.

Question
Copperas (crude ferrous sulfate) is purified by dissolving it in water and recrystallizing
it in a crystallizer. First, copperas is dissolved in pure water to give a solution containing
28% FeSO4 (by weight). The solution is cooled to 10
0C to give out the crystals of
FeSO47H2O crystals. The original copperas contains 96% FeSO47H2O (by weight). Find
the quantity of copperas charged to the crystallizer. The solubility of FeSO4 at 10 0C is
20.51 g per 100 g water. Assume that the solubility of FeSO4 at 100C is unaffected by the
impurities present in copperas.
