Question

 26. (a) Calculate the mass of potassium chloride required to prepare its 40% (mass %) solution in 100g water?  (b) 100ml of water is taken at 298K in a beaker and a little of solid A is dissolved in it with constant stirring to obtain solution ‘B’. More and more of solid ‘A’ is added to the solution with constant stirring while keeping the temperature of the solution constant at 298K. After sometime , it was observed that no more solid dissolves but at the same time some solid is left undissolved at the bottom of the beaker. The contents of the beaker are filtered to obtain filtrate ‘C’. 
(i) What are solutions ‘B’ and ‘C’ called? 
(ii) What term is used to denote the amount of solid ‘A’ dissolved in 100g of water at 298K.
