Question
There are some of the characteristics of the supersaturated solution
I : Equilibrium exists between solutions and solid solute
II : If a crystal of solute is added to supersaturated solution, crystallisation occurs rapidly
III : Supersaturated solutions contain more solute than they should have at a particular temperature
Correct characteristics of supersaturated solutions are :
I : Equilibrium exists between solutions and solid solute
II : If a crystal of solute is added to supersaturated solution, crystallisation occurs rapidly
III : Supersaturated solutions contain more solute than they should have at a particular temperature
Correct characteristics of supersaturated solutions are :
Options
A.I, II, III
B.II, III
C.I, III
D.I, II
Solution
Supersaturated solutions are not in equilibrium with the solid substance. Thus if a small crystal of solute (say sodium thiosulphate) is added to its supersaturated solution, the excess immediately crystallises out, which is usually quite fast.
