What is value of ebullioscopic constant?
56 K kg mol – 1. Hint: The ebullioscopic constant of water depends upon the molar mass of the solute in the solution. This constant relates the molality of a solution to the elevation in boiling point which is directly proportional to the molality of the solution.
What does the ebullioscopic constant depend on?
Ebullioscopic constant depends on number of solvent molecules.
What is the ebullioscopic constant of benzene?
B5: Ebullioscopic (Boiling Point Elevation) Constants

|---|---|
| Benzene | 2.64 |
| 1-Butanol | 2.17 |
| Carbon disulfide | 2.42 |

What is Ebullioscopic method?
An ebullioscope (from the Latin ēbullīre (to boil) + -scope) is an instrument for measuring the boiling point of a liquid. This can be used for determining the alcoholic strength of a mixture, or for determining the molecular weight of a non-volatile solute based on the boiling-point elevation.
What is ebullioscopic constant in chemistry?
In thermodynamics, the ebullioscopic constant Kb relates molality b to boiling point elevation. It is the ratio of the latter to the former: i is the van ‘t Hoff factor, the number of particles the solute splits into or forms when dissolved. b is the molality of the solution.
What is ebullioscopic constant write note on mole fraction?
Solution. Ebullioscopic constant: Ebullioscopic constant or Molal elevation constant is the elevation in the boiling point produced when one mole of the solute is dissolved in one kilogram of solvent. Its unit is K kg mol-1.
What is ebullioscopic constant explain the determination of molecular mass of solute by using elevation of boiling point?
What is molar elevation constant or ebullioscopic constant?
Molal elevation constant can be defined as the elevation in boiling point produced when one mole of solute is dissolved in 1 kg i.e. 1000 g of the solvent. It is also known as the ebullioscopic constant.
What is ebullioscopic constant shaala?
