Paragraph: Colligative properties are very important properties of the solution. These properties are based on amount of solute and solvent only. They do not depend upon the identity of the particles. The vapour pressures of pure ethanol and pure methanol are 44 mmHg and 88 mmHg at a certain temperature T(K) . They form an ideal solution Paragraph: Select the correct statement.

Options

  1. AVapour pressure is a colligative property
  2. BFluid inside the blood cell is isotonic with 0.9 % ~W / V NaCl solution
  3. CEbullioscopic or cryoscopic constants are properties of solution only
  4. DSpreading NaCl on the ice deposited on road will cause increase of freezing point

Correct answer

B. Fluid inside the blood cell is isotonic with 0.9 % ~W / V NaCl solution

Step-by-step solution

k_b or k_f are the properties of solvent only.
