Identify the correct statements for ideal solution.
(A) It obeys Raoult's law over the entire range of concentration.
(B) It shows a positive deviation from Raoult's law.
(C) In an ideal solution, solvent-solute, solute-solute and solvent-solvent molecular interactions are comparable.
(D) The volume change i.e. ΔmixV=0\Delta_{\text{mix}}V = 0
(E) The enthalpy change i.e. ΔmixH=0\Delta_{\text{mix}}H = 0
Choose the correct answer from the options given below:

Options

  1. A(A), (B) and (D) only.
  2. B(A), (C), (D) and (E) only.
  3. C(A), (B), (C) and (D) only.
  4. D(B), (C), (D) and (E) only.

Correct answer

B. (A), (C), (D) and (E) only.

Step-by-step solution

An ideal solution is defined as a solution that obeys Raoult's law over the entire range of concentration. Thus, statement (A) is correct and statement (B) is incorrect.

For an ideal solution, the intermolecular attractive forces between the solute-solute and solvent-solvent molecules are nearly equal to those between solute-solvent molecules. Thus, statement (C) is correct.

Since the interactions are similar, there is no change in volume or enthalpy upon mixing. Therefore, ΔmixV=0\Delta_{\text{mix}}V = 0 and ΔmixH=0\Delta_{\text{mix}}H = 0. Thus, statements (D) and (E) are correct.

The correct statements are (A), (C), (D) and (E).

Answer: (A), (C), (D) and (E) only.
