Question
Define the following terms:
- Mole fraction.
- Isotonic solutions.
- Van't Hoff factor.
- Ideal solution.
✓
Answer
- Mole fraction is the ratio of number of moles of one component to the total number of moles in a mixture.
- Two solutions having same osmotic pressure at a given temperature are called Isotonic Solutions.
- Van’t Hoff factor is expressed as:
$\text{i}=\frac{\text{Normal molar mass}}{\text{abnormal molar mass}}$
- The solution which obeys Raoult’s law under all conditions is known as an ideal solution.
