1 kg of a saturated aqueous solution of a highly soluble component A at 60°C is cooled to 25°C. The solubility limits of A are (0.6 kgA/kg water) at 60°C and (0.2 kgA/kg water) at 25°C. The amount in kg of the crystals formed is________________________?
Correct answer: C
Explanation
The amount of crystals formed is the difference between the initial solubility and the final solubility. Crystals = 0.6 - 0.2 = 0.4 kgA/kg water.
