Formation of a solution from two components can be considered as (1). pure solvent`to`separated solvennt molecules, `DeltaH_(1)` (2). Pure solute `to`separated solute molecules, `DeltaH_(2)` (3). Separated solvent and solute molecules`to`solution, `DeltaH_(3)` Solution so formed will be ideal ifA. `DeltaH_("soln")=DeltaH_(1)-DeltaH_(2)-DeltaH_(3)`B. `DeltaH_("soln")=DeltaH_(3)-DeltaH_(1)-DeltaH_(2)`C. `DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH_(3)`D. `DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH-DeltaH_(3)`

Answer» Correct Answer - C
For ideal solution,
`DeltaH_("solution")=DeltaH_(1)+DeltaH_(2)+DeltaH_(3)`
