The correct Answer is:
To find the elevation of boiling point when a non-volatile solute is added to a solvent, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Boiling Point Elevation**: - When a non-volatile solute is added to a solvent, the boiling point of the solvent increases. This phenomenon is known as boiling point elevation. 2. **Identify the Given Variables**: - Let \( T_1 \) be the boiling point of the solution. - Let \( T_2 \) be the boiling point of the pure solvent. 3. **Use the Formula for Boiling Point Elevation**: - The elevation in boiling point (\( \Delta T_b \)) can be expressed as: \[ \Delta T_b = T_1 - T_2 \] - This equation states that the boiling point of the solution (\( T_1 \)) is equal to the boiling point of the pure solvent (\( T_2 \)) plus the elevation in boiling point (\( \Delta T_b \)). 4. **Conclusion**: - Therefore, the elevation of boiling point can be calculated as: \[ \Delta T_b = T_1 - T_2 \] ### Final Answer: The elevation of boiling point is given by \( \Delta T_b = T_1 - T_2 \). ---

Elevation Of Boiling Point|Summary

For a dilute solution containing a nonvolatile solute, the molar mass of solute evaluated from the elevation of boiling point is given by the experssion:

Boiling point elevation is

The molal elevation constant is the ratio of the elevation in boiling point to :

Statement-1 : In binary ideal solution more volatile component boils at less temperature and less volatile component boils lat high temperature than their normal boiling point of pure component. Statement-2 : For any composition, mixture boils at temperature in between their normal boiling point temperature of pure component.

Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperaure and elevation in boiling point is marked. Given that DeltaT_(b) is the elevation in boiling point of the solvent in a solution of molarity m then lim_(m rarr 0) ((Delta T_(b))/(m)) is equal to:
