Question

What does point $A$ and $B$ represent in the following diagram?

• A. (Point A)-Boiling point of solvent, (Point B)-Boiling point of solution
• B. (Point A)-Boiling point of solution, (Point B)-Boiling point of solvent
• C. (Point A)-Boiling point of solute, (Point B)-Boiling point of solvent
• D. (Point A)-Boiling point of solvent, (Point B)-Boiling point of solute

Answer 1

Answer: (A)

Since, boiling point of a solution is always higher than that of pure solvent and from figure $B>A$. So, $B$ is the boiling point of solution and $A$ is of pure solvent.
