What are the differences between ideal and non-ideal solution?

Basis of differentiation

Ideal solution

Non-ideal solution

Definition

Is a solution in which interactions between molecules are identical between all molecules in the solution

Is a solution that has differences in the interactions between molecules of different substances in the solution

Change in enthalpy

The change in enthalpy is zero 

The change in enthalpy is a positive or negative value 

Composition

Are highly dilute solutions

Are concentrated solutions

Components

Components behave independently

Components interact with one another
