Question

If liquids A and B form an ideal solution

• A. the enthalpy of mixing is zero
• B. the entropy of mixing is zero
• C. the free energy of mixing is zero
• D. the free energy as well as the entropy ofmixing are each zero

Answer 1

Answer: (A)

If liquids A and B form ideal solutions, $\Delta H_{mix} $and $\Delta V_{mix}$ must be zero.
