The elevation in boiling point โ๐๐ is equal to ebullioscopic constant ๐พ๐ when the Molarity (๐) of the solution is:
Correct answer: D. Statement is wrong
- A. 0.1m
- B. 1.0m
- C. 10.0m
- D. Statement is wrong
Explanation
According to the formula for the elevation of boiling point โTb=kbรm Where kb is the ebullioscopic constant and m is the molality of the solution. โTb will be equal to kb only if molality is 1.0m and it has no relation with the molarity of solution so the given statement is wrong.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
