An aqueous solution of potassium hydroxide is fed at a rate of 875 kg/h to an evaporative
Question:
An aqueous solution of potassium hydroxide is fed at a rate of 875 kg/h to an evaporative crystallizer operating at 10°C, producing crystals of KOH∙2H2O. A 5 g aliquot of the feed solution is titrated to neutrality with 22.4 mL of 0.85 molar H2SO4. The solubility of KOH at 10°C is 103 kg KOH/100 kg H2O. At what rate must water be evaporated to crystallize 60% of the KOH in the feed?
