A batch of saturated aqueous solution of barium chloride is prepared at 90 C and sent to a batch cooling crystallizer operating at 10 °C. The products of the crystallization process are dihydrate crystals. 1000 kg of water is used for the preparation of the saturated solution of barium chloride at 90 C. The solubility data of barium chloride in water is given in Table Q3. (c) Table Q3: Solubility of Barium Chloride in Water Compound Solubility, kg anhydrous compound/100kg water 20 °C 40 °C 60 °C 80 °C 100 °C Barium chloride, | 31.6 BaCl, 35.7 40.7 46.4 52.4 58.6 Given: MW of anhydrous BaCl2 = 208.23 g/mol; MW of water =18.016 g/mol; MW of BaCl2 2H2O=244.26 g/mol. (i) Calculate the weight of anhydrous barium chloride required for dissolution to prepare the saturated solution at 90 C. (ii) Calculate the weight of the crystals produced.
