# Difference between Ideal Solution and Non-ideal Solution

A solution is a homogeneous mixture of two or more substances. The substance present in the greatest amount is known as the solvent, which determines the physical state of the solution. Other substances dissolved in the solvent are called solutes. When a solution is made of two components, it is called a binary solution. The properties of solutions, such as vapor pressure, boiling point, freezing point, and other colligative properties, are essential for understanding their behavior.

## Ideal Solution

An ideal solution is characterized by the fact that the interactions between solute-solute (A-A) and solvent-solvent (B-B) molecules are similar to those between solute-solvent (A-B) molecules. An ideal solution meets the following criteria:

1. Adherence to Raoult’s Law: Ideal solutions comply with Raoult’s law across all concentrations and temperature ranges. This law states that the partial vapor pressure of each component in the solution is directly proportional to its mole fraction at a given temperature.
2. Enthalpy of Mixing: The mixing of components in an ideal solution does not absorb or release heat, meaning the enthalpy of mixing (ΔHmix) is zero.
3. Volume of Mixing: The volume of the ideal solution is simply the sum of the volumes of the individual components, indicating that the volume of mixing (ΔVmix) is zero.

Ideal solutions are typically formed by components of similar size and polarity, with no association, dissociation, or reaction occurring between them. While perfect ideal solutions are rare, some solutions closely approximate ideal behavior. Examples include mixtures like benzene and toluene, hexane and heptane, bromoethane and chloroethane, and chlorobenzene and bromobenzene.

## Non-Ideal Solution

Non-ideal solutions are those that do not adhere to Raoult’s law across all concentrations and temperatures. Such solutions exhibit either positive or negative deviations from Raoult’s law. The enthalpy and volume of mixing for non-ideal solutions are not zero.

## Positive Deviation

In a non-ideal solution showing positive deviation, the total vapor pressure is higher than predicted by Raoult’s law. This occurs when the interactions between solute and solvent molecules (A-B) are weaker than those between the molecules of the pure components (A-A and B-B). As a result, the enthalpy of mixing (ΔHmix) and volume of mixing (ΔVmix) are positive. Examples of such solutions include ethanol and acetone, carbon disulfide and acetone, and acetone and benzene.

## Negative Deviation

In contrast, a non-ideal solution exhibiting negative deviation has a total vapor pressure lower than that predicted by Raoult’s law. Here, the interactions between solute and solvent molecules (A-B) are stronger than those between the molecules of the pure components. Consequently, the enthalpy of mixing (ΔHmix) and volume of mixing (ΔVmix) are negative. Examples include mixtures like phenol and aniline, and chloroform and acetone.

## Key Differences Between Ideal and Non-Ideal Solutions
