Non-ideal solution

A non-ideal solution is a mixture where the components do not interact perfectly as they do in an ideal solution. In such solutions, the molecules may attract or repel each other differently than in pure substances, leading to behaviors like uneven mixing or changes in properties such as boiling point and vapor pressure. These deviations happen because the interactions between different types of molecules are not the same as those between similar molecules. Essentially, non-ideal solutions reflect real-world behavior where interactions are complex and do not follow simplified rules, requiring more detailed understanding or calculations.
