Question

Statement 1: $\Delta H_{\text{mix }}$ and $\Delta V_{\text{mix }}$ in an ideal solution are zero
Statement 2: $A-B$ interactions in ideal solutions are same as between $A-B$ and $B-B$

• A. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
• B. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
• C. Statement 1 is True, Statement 2 is False
• D. Statement 1 is False, Statement 2 is True

Answer 1

Answer: (A)

An ideal solution of the components $A$ and $B$ is defined as the solution in which the intermolecular interactions between $A$ and $B$ are the same magnitude as between the pure components or it is a solution there is no volume change or enthalpy change or mixing
