Question

Match the following aqueous solutions with the appropriate letter from the column on the right.

1. 0.17 m KNO3 A. Highest boiling point

2. 0.11m Na3PO4 B. Second highest boiling point

3. 0.18m KNO3 C. Third highest boiling point

4. 0.39 m Ethylene glycol (nonelectrolyte) D. Lowest boiling point

Answer 1

1. 0.17m KNO₃        C.Third boiling point

2.0.11m Na3PO4 A.Highest boiling point

3.0.18m KNO3 B.second boiling point

4.0.39m ethylene glycol             D.Lowest boiling point

In colligative properties There is an elevation of boiling point by the addition of salts.Here Na3PO4 dissociates into 4 ions ,so it is having high boiling point.then 0.18m KNO3 has more concentration.so it has next boiling point.Ethylene glycol is an organic comound has least boiling point.
