Question

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

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

(A) ${\Delta }_{min}H=0$, ${\Delta }_{min}V=0$ $⟶$ ideal solution

(B) ${\Delta }_{mix}H\ne 0$, ${\Delta }_{mix}V\ne 0$ $⟶$ Non-ideal solution

(C) ${\Delta }_{mix}H<0$, ${\Delta }_{mix}V<0$ $⟶$ Negative deviation

(D) ${\Delta }_{mix}H>0$, ${\Delta }_{mix}V>0$ $⟶$ Positive deviation.
