Boiling Point Elevation Salt

Boiling Point Elevation Salt. In particular the temperature at which the vapor pressure is 1 atm will be higher than the normal boiling point by an amount known as the boiling point elevation. K b 0512 oCm.

For example the boiling point of pure water at 10atm is 100oC while the boiling point of a 2 salt-water solution is about 102oC. The temperature at which the solvent boils is increased by adding any non-volatile solute. It occurs any time you add a nonvolatile solute such as salt to a solvent such as water.

Use the measured results of normal boiling temperature nT b of solvent in the equation 2.

So a big spoon of salt in a pot of water will increase the boiling point by four hundredths of a degree. Vapor pressure measurement of the salt solution provides a direct determination of. A common example of boiling point elevation can be observed by adding salt. It occurs any time you add a nonvolatile solute such as salt to a solvent such as water.
