Explain the terms ideal and non-idealsolution in the light of forces of interactions operating between molecules in liquid solutions.

Explanation

To explain the terms "ideal" and "non-ideal" solutions in the context of the forces of interaction operating between molecules in liquid solutions, we can break down the concepts as follows:

### Step 1: Definition of Ideal Solution
An **ideal solution** is defined as a solution that obeys Raoult's Law at all concentrations and temperatures. In an ideal solution, the interactions between the different molecules (solute and solvent) are similar to the interactions between the molecules of the pure components.

**Key Characteristics of Ideal Solutions:**
- The total vapor pressure of the solution is the sum of the partial pressures of the individual components.
- The enthalpy change (ΔH) during mixing is zero, indicating that there is no heat absorbed or released during the dissolution process.
