Question

100 ml of water is taken at 298k in a beaker and a little of solid 'A' is dissloved 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 sometimes,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 contests of the beaker are filtered to obtain filtrate 'C'.


i) What are the solutions B and C called?
ii) What will happen when the solution c at 298 k is cooled down to 283k by keeping the beaker in crushed ice?
iii) Which term is used to denote the amount of solid dissolved in 100 grams of water at 298k?​

Answer 1

Answer:

(I)

B- unsaturated solution

C- saturated solution

(ii)

Crystalisation will take place

(solubility)
