Extracted text: 3. Naci crystals are produced from 1000 kg of solution containing 10% NaCI, 1% KOH, and 89% H20. The solution is first sent to an evaporator where 750 kg of water from the wtsolution is removed. The hot concentrated solution is sent to a crystallizer where the solution is cooled to 20°C and NaCl crystals are precipitated. No water evaporates. Each kilogram of crystals caries with it 0.10 kg of adhering mother liquor. The wet crystals are then treated in a dryer where 95% of the water is removed. Calculate: a. The compositions of the concentrated solution from the evaporator b. The composition of the final product and c. The percentage recovery of NaCi from the original solution. The solubility of NaCl is 36 grams NaCI/ 100 grams H;0 at 20°C.
