Choose the correct statement.

Options

  1. AFor a solvent, K_b= R M₁ T_b^2 1000 Hvap ( R = . Gas constant, M₁= Molar mass of solvent, T_b=B . P of the sol
  2. BHypotonic solution is more concentrated with respect to the other solution separated by a semi permeable membr
  3. CA 1.0 molal solution of Glucose in water is more concentrated than 1.0 M glucose solution in the same solvent.
  4. DA solution formed by adding Carbon di-sulphide to Acetone forms a maximum boiling azeotrope.

Correct answer

A. For a solvent, K_b= R M₁ T_b^2 1000 Hvap ( R = . Gas constant, M₁= Molar mass of solvent, T_b=B . P of the sol

Step-by-step solution

(1) Correct: K_b = R M₁ T_b^2 1000 H_ vap is the standard thermodynamic expression for the ebullioscopic constant, where R is the gas constant, M₁ is the molar mass of solvent, T_b is the boiling point of pure solvent, and H_ vap is the molar enthalpy of vaporization. (2) Incorrect: A hypotonic solution has lower solute concentration. The solution with higher concentration is called hypertonic. (3) Incorrect: 1.0 M solution has 1 mole of glucose in 1 L of solution (less than 1 kg of solvent), while 1.0 m solution h
