Question

Match the column $I$ with column $II$ and mark the appropriate choice.

Column I		Column II
(A)	$\Delta H_{mix}=0$, $\Delta V_{mix}=0$	(i)	Non-ideal solution
(B)	$\Delta H_{mix}\ne 0$, $\Delta V_{mix}\ne 0$	(ii)	Positive deviation
(C)	$\Delta H_{mix}<0$, $\Delta V_{mix}<0$	(iii)	Ideal solution
(D)	$\Delta H_{mix}>0$, $\Delta V_{mix}>0$	(iv)	Negative deviation

• A. $(A)\to (i)$, $(B)\to (iii)$, $(C)\to (ii)$, $(D)\to (iv)$
• B. $(A)\to (iii)$, $(B)\to (i)$, $(C)\to (iv)$, $(D)\to (ii)$
• C. $(A)\to (ii)$, $(B)\to (iii)$, $(C)\to (iv)$, $(D)\to (i)$
• D. $(A)\to (iii)$, $(B)\to (ii)$, $(C)\to (i)$, $(D)\to (iv)$

Answer 1

Answer: (B)

(A) ${\Delta }_{\min }H=0,{\Delta }_{\min }V=0⟶$ ideal solution
(B) ${\Delta }_{\text{mix }}H\ne 0,{\Delta }_{\text{mix }}V\ne 0⟶$ Non-ideal solution
(C) ${\Delta }_{\text{mix }}H<0,{\Delta }_{\text{mix }}V<0⟶$ Negative deviation
(D) ${\Delta }_{\text{mix }}H>0,{\Delta }_{\text{mix }}V>0⟶$ Positive deviation.
