1.	Amount of solutes A,B and C in 500 g of water at 30^(@)C ,60^(@)C , 100^(@)Cin their saturated solutions are given below. {:(,30^(@)C,60^(@)C,100^(@)C),(A,140 g, 135 g,131 g),(B,160 g, 175 g, 182 g ),(C,152 g, 170 g, 161 g):} When the hot saturated solutions of A, B and C are cooled slowly, identify the order in which they crystallize out of a solution. Give reason in support of your answer.
Answer» Solution :(i) comparision of changes in soubilities with change in temperature. (ii) Comparision of change is solubilities with decrease in temperature from `100^(0)C` to `30^(0)C . (III) Effect of COOLING on nature of the solutions of A , B, C respectively. (iv) Relation between extent of SOLUBILITY and crystallization.
