Glaubers salt is made by crystallization from a water solution at 200C. The aqueous solution at 200C contains 8.4% sodium sulfate. How many grams of water must be evaporated from a liter of such solution whose specific gravity is 1.077 so that when the residue solution after evaporation is cooled to 200C, there will be crystallized out of 80% of the original sodium sulfate as Glaubers salt? The solubility of sodium sulphate in equilibrium with the decahydrate is 19.4 g Na2SO4 per 100 g H2O.
