The correct Answer is:
To solve the question regarding the elevation of boiling point when a solute is added to a solvent, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Boiling Point Elevation**: - When a non-volatile solute is dissolved in a solvent, the boiling point of the resulting solution is higher than that of the pure solvent. This phenomenon is known as boiling point elevation. 2. **Identifying the Variables**: - Let \( T_1 \) be the boiling point of the solution. - Let \( T_2 \) be the boiling point of the pure solvent. 3. **Defining Elevation of Boiling Point**: - The elevation of boiling point, denoted as \( \Delta T_b \), is defined as the difference between the boiling point of the solution and the boiling point of the solvent. 4. **Writing the Formula**: - The formula for the elevation of boiling point can be expressed as: \[ \Delta T_b = T_1 - T_2 \] - Here, \( \Delta T_b \) represents the increase in boiling point due to the presence of the solute. 5. **Conclusion**: - Therefore, the elevation of boiling point is given by the equation \( \Delta T_b = T_1 - T_2 \). ### Final Answer: The elevation of boiling point is given by \( \Delta T_b = T_1 - T_2 \). ---
