Which of the following is not a characteristic of an ideal solution? (2019)

Step 1: Understand what an ideal solution is. An ideal solution is a mixture of two or more substances that behaves in a predictable way according to certain laws.
Step 2: Learn about Raoult's law. This law states that the vapor pressure of a solution is directly related to the concentration of the components in the solution.
Step 3: Know that an ideal solution has a constant boiling point. This means that the temperature at which the solution boils does not change as the composition changes.
Step 4: Identify the characteristics of an ideal solution. These include obeying Raoult's law and having a constant boiling point.
Step 5: Recognize that variable composition means the proportions of the components in the solution can change. This is not a characteristic of an ideal solution.
