AIPMT PRELIMS 2003 Chemistry Ideal Solutions MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Formation of a solution from two components can be considered as: (i) Pure solvent →\rightarrow separated solvent molecules, ΔH1\Delta H_1 (ii) Pure solvent →\rightarrow separated solvent molecules, ΔH2\Delta H_2 (iii) Separated solvent and solute molecules →\rightarrow solution, ΔH3\Delta H_3 Solution so formed will be ideal if:

A

ΔHsoln=ΔH¹+ΔH²+ΔH3\Delta H_{\text{soln}} = \Delta H_¹⁺ \Delta H_²⁺ \Delta H_3

B

ΔHsoln=ΔH¹+ΔH²−ΔH3\Delta H_{\text{soln}} = \Delta H_¹⁺ \Delta H_²⁻ \Delta H_3

C

ΔHsoln=ΔH¹−ΔH²−ΔH3\Delta H_{\text{soln}} = \Delta H_¹⁻ \Delta H_²⁻ \Delta H_3

D

ΔHsoln=ΔH¹−ΔH²+ΔH3\Delta H_{\text{soln}} = \Delta H_¹⁻ \Delta H_²⁺ \Delta H_3

Correct Answer

Option A

Detailed Explanation

For an ideal solution, the enthalpy of mixing is zero, so ΔHsoln=ΔH¹+ΔH²−ΔH3\Delta H_{\text{soln}} = \Delta H_¹⁺ \Delta H_²⁻ \Delta H_3.
