MCQ
For which solution the value of Van't hoff factor is not equal to 1?
- AGlucose
- BSugar
- CFructose
- DAcetic acid
✓
Answer
- Acetic acid
Explanation:
Glucose, sugar and fructose are non- electrolytes, acetic acid is weak elecrolyte and hence dissociates in hydrogen and acetate ions.
Colligative property depends on number of particles present in the solution.
van't Hoff factor is ratio of observed colligative property to theoretical colligative property.
Therefore, van't Hoff factor of acetic acid is greater than 1.
