formation of a solution form two components can be considered as
(i) Pure solvent rarr separated solvent molecules, `DeltaH_(1)`
(ii) Pure solute rarr separated solute molecules, `DeltaH_(2)`
(iii) separated solvent and solute molecules rarr solution, `DeltaH_(3)`
Solution so formed will be ideal if

`Delta H_("soln")=Delta H_(3)-Delta H_(1)-Delta H_(2)`

`Delta H_("soln")=Delta H_(1)+Delta H_(2)+Delta H_(3)`

`Delta H_("soln")=Delta H_(1)-Delta H_(2)-Delta H_(3)`

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 if

`DeltaH_("soln")=DeltaH_(1)-DeltaH_(2)-DeltaH_(3)`

`DeltaH_("soln")=DeltaH_(3)-DeltaH_(1)-DeltaH_(2)`

`DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH_(3)`

`DeltaH_("soln")=DeltaH_(1)+DeltaH_(2)+DeltaH-DeltaH_(3)`

`Delta H_("soln") = DeltaH_3-DeltaH_1-DeltaH_2`

`DeltaH_("soln") = DeltaH_1 + DeltaH_2 + DeltaH_3`

`DeltaH_("soln") = DeltaH_1 + DeltaH_2 - DeltaH_3`

`DeltaH_("soln") = DeltaH_1 - DeltaH_2 - DeltaH_3`

`/_\H_("soln")=/_\H_(1) + /_\H_(2) +/_\H_(3)`

`/_\H_("soln")=/_\H_(1) + /_\H_(2) -/_\H_(3)`

`/_\H_("soln")=/_\H_(1) -/_\H_(2) -/_\H_(3)`

`/_\H_("soln")=/_\H_(3) - /_\H_(1) -/_\H_(2)`
