Which of the following solutions is an example of an ideal solution?
Ethanol and Acetone
Acetone and water
Sodium chloride and water
Carbon tetrachloride and chloroform
Carbon tetrachloride and chloroform is an example of an ideal solution because both components are nonpolar liquids and have similar molecular sizes and London dispersion forces. Thus, they have similar intermolecular interactions and can mix homogeneously without any significant change in volume or heat. Therefore, the enthalpy of mixing and activity coefficients of each component are close to unity, and the entropy of mixing is negative.
