Given:-
is the molality of the solution and it is defined as the number of moles of solute dissolved of solvent.
Boiling point =
Step-by-step explanation
Step 1.
First, let us see what a Van't Hoff factor is. Van't Hoff factor (i) is the relationship between the apparent number of moles of solute added in solution determined by the colligative property and the actual number of moles of solute added in order to form a solution. The Van't Hoff factor is the measurement of the deviation from the ideal behavior. In order to find the Van't Hoff factor, we have to make use of the following formula.
......(1)
where,
- is the boiling point elevation. This is one of the colligative properties. When a solute is added the boiling point of the solution will increase. This is known as the boiling point elevation.
- - The boiling point of the solution is
- is the boiling point elevation.
- is the ebullioscopic constant and it is given as
- is the molality of the solution and it is defined as the number of moles of solute dissolved in of solvent.
