[Crystallization] A saturated solution of NażSO4 at 30°C is cooled in a crystallizer to a saturated solution at 15°C. How many kg of Glauber's Salt, Na2SO4.10H2O is expected to be produced from a metric ton of the solution at 30°C if (a) no water is evaporated and (b) 10% of the original water in the solution is lost by evaporation? Solubility at 15°C is 13.5 parts and at 30°C, 40 Na;SO4 per 100 parts water.

Topic : Material balance without chemical Reactions (single unit)

[Crystallization] A saturated solution of NazSO4 at 30°C is cooled in a crystallizer to a
saturated solution at 15°C. How many kg of Glauber's Salt, NazSO4.10H20 is expected to be
produced from a metric ton of the solution at 30°C if (a) no water is evaporated and (b) 10%
of the original water in the solution is lost by evaporation? Solubility at 15°C is 13.5 parts and
at 30°C, 40 Na,SO4 per 100 parts water.
