Which of the following solutions would be considered as an ideal solution?
Ethanol and Acetone
Benzene and Acetone
Acetone and chloroform
Nitrogen and oxygen
Nitrogen and oxygen are both non-polar molecules and have similar intermolecular forces. They both have London dispersion forces as the only intermolecular force. Hence, they would form an ideal solution. The solution of nitrogen and oxygen would be considered as an ideal solution because both components are nonpolar gases and have similar sizes and intermolecular forces. They 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.
