What is Ideal Solution?
A solution that obeys Raoult's law over all compositions and concentrations. In an ideal solution, solute-solvent interactions are equal to solvent-solvent and solute-solute interactions. Mixing is neither endothermic nor exothermic. Few real solutions are truly ideal.

The ideal solution model is the reference state for real solutions (activity = concentration for ideal solutions). It simplifies calculations in vapour-liquid equilibrium, osmotic pressure (Van't Hoff equation assumes ideal dilute solution), and phase diagrams. Departures from ideality are quantifie…
No direct safety concern. Real solutions that deviate positively from Raoult's law (azeotropes) may have lower boiling points than expected — relevant for design of distillation operations and prevention of unexpected vapour accumulation in confined spaces.
The formula or notation for Ideal Solution is: Ideal solution: Raoult's law holds; ΔH_mix = 0, ΔV_mix = 0
