Define an ideal solution and write one of its characteristics.

Explanation

### Step-by-Step Text Solution

**Step 1: Define an Ideal Solution**
An ideal solution is defined as a solution in which the interactions between the molecules of the different components are similar to the interactions between the molecules of each individual component. In other words, the attractive forces between like molecules (A-A and B-B) are equal to the attractive forces between unlike molecules (A-B). This condition leads to the solution obeying Raoult's Law.

**Step 2: Explain Raoult's Law**
Raoult's Law states that the partial vapor pressure of each component in an ideal solution is directly proportional to its mole fraction in the solution. This means that the behavior of the solution can be predicted based on the concentrations of the components.
