Evaluate the following statements for their correctness.

A. The elevation in boiling point temperature of water will be same for 0.1 M NaCl and 0.1 M urea.

B. Azeotropic mixture boil without change

Question

Evaluate the following statements for their correctness.

A. The elevation in boiling point temperature of water will be same for 0.1 M NaCl and 0.1 M urea.

B. Azeotropic mixture boil without change in their composition.

C. Osmosis always takes place from hypertonic to hypotonic solution.

D. The density of 32%  solution having molarity 4.09 M is approximately 1.26 g mL⁻¹.

E. A negatively charged sol is obtained when KI solution is added to silver nitrate solution.

Choose the correct answer from the options given below:

Canvas Classes · Accepted Answer

Strategy:
 Evaluate chemical statements by applying colligative property laws, concentration conversions, and definitions of solution types.

Evaluation:
- A.  () vs Urea (). At same ,  gives double the particles, so elevations differ. Incorrect.
- B. Azeotropes have identical composition in liquid and vapour, so they boil at a constant temperature without changing composition. Correct.
- C. Osmosis is solvent movement from low solute (Hypotonic) to high solute (Hypertonic). Incorrect.
- D. Rela
