difference between molar and molal elevation constant Molar elevation constant Molar 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
We can express the relationship between T b and concentration as follows T b mK b label eq2 where m is the concentration of the solute expressed in molality and K b is the molal boiling point elevation Boiling point elevation is the difference in temperature between the boiling point of the pure solvent and that of the solution The molal boiling point elevation constant is equal to the

According to Table PageIndex 1 the molal boiling point elevation constant for water is 0 51 C m Thus a 1 00 m aqueous solution of a nonvolatile molecular solute such as Boiling point of solution boiling point of pure solvent boiling point elevation T b The elevation in boiling point T b is proportional to the concentration of the solute in the solution It can be calculated via the following equation T b
Where K b is the boiling point elevation constant or the ebullioscopic constant and m is the molal concentration molality of all solute species Boiling point elevation constants are Molar Mass from Boiling Point Elevation or Freezing Point Depression The addition of a nonvolatile solute to a solvent causes the boiling point of the solvent to increase and the freezing point of the solvent to decrease molar mass
