Hello students, considering the first system which is an unsaturated solution of sodium chloride in water.
00:10
As sodium chloride is completely soluble in water and hence they will create only one phase.
00:19
As the number of components is sodium chloride and water and hence there are two components.
00:26
The degree of freedom which is given as c minus p plus 2.
00:34
Substituting the value of number of components which is 2 minus number of phases which is 1.
00:42
The degree of freedom comes out to be 3.
00:46
The second system is a saturated solution of sodium chloride in water with excess of sodium chloride solid present.
00:56
As sodium chloride is present in excess it will create two phases.
01:03
One with the solid phase of sodium chloride and one is the solution phase.
01:09
The number of components is 2.
01:12
They are sodium chloride and water.
01:15
Substituting the value of number of components which is 2, number of phases which is also 2.
01:22
The degree of freedom comes out to be 2.
01:26
For the third system an unsaturated solution of sodium chloride and sucrose in water.
