2. (30 points) An aqueous solution of Na2CO3 contains 12% carbonate and small amounts of soluble impurities, 80% of the carbonate is recovered as Na₂CO3-10H₂O by evaporation of water and subsequent cooling in a crystallizer to 41°F. The solubility of Na₂CO3 at 41°F is 9.0% (weight). On the basis of 100 kg solution treated, determine the following: a. The amount of water evaporated. b. The quantity of crystals formed.
