100 ml of water at room temperature of 25 degree Celsius is taken in a beaker and a little solid S is dissolved in it by stirring to obtain solution X more of solid S is added to the solution with constant steering while keeping the temperature of the solution constant at 30 degree Celsius. After sometime it is observed that no more solid dissolves in water and at the same time some solid is also left and dissolved at the bottom of the beaker the contents of the beaker are filtered through a filter paper to obtain solution why in the form of filtrate.
(a) what is the solution like X called?
(b) what is the solution like Y called?
(c) what will you observe if the solution Y at 30 degree celsius is cool down to 10 degree Celsius by keeping the beaker in crushed ice?Why?
(d) what term is used to denote the solid dissolved in 100 grams of water in solution like Y?
Answers & Comments
a- saturated solution
b-unsaturated solution
c-the solute which you have dissolve will come out at the surface in the form of crystals
d-solute
when no More solute can be dissolve then it is called saturated solution
hope it will helps you
Answer:
Some of the dissolved solid will separate from the solution and settle down at the bottom of the beaker; Because the solubility of solid decreases on coolit
