Question:

The enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is also zero. This statement is valid for which of the following solution?

Options:

Non-ideal showing positive deviation

Non-ideal showing negative deviation

Azeotropic mixture

Ideal solution

Correct Answer:

Ideal solution

Explanation:

The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. The ideal solutions have two other important properties. The enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is also zero, i.e., ∆mixH = 0, ∆mixV = 0
