6. 100kg of a saturated solution of copper sulphate (CuSO45H2O) salt is cooled in a batch crystallizer from 100C to 30C. Given that the solubility of copper sulphate in water is 114g / 100g water and 37.8g/100g water at 100 and 30C, respectively. Determine: (a) Yield of hydrated salt if no evaporation occurs (b) Yield of hydrated salt if 15% of water is evaporated Molecular weight of Cu=63.5;S=32.0;H=1.0;O=16.0 Ans: (a) 70.8kgCuSO4.5H2O; (b) 76.1kgCuSO45H2O
