Answer» on of boiling point:Boiling-point elevation DESCRIBES the phenomenon that the boiling point of a LIQUID will be higher when another compound is added, meaning that a SOLUTION has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. Boiling point elevation occurs when the boiling point of a solution becomes higher than the boiling point of a pure solvent. The temperature at which the solvent boils is increased by adding any non-volatile solute.Boiling-Point Elevation EXAMPLE: Kb for water is 0.51 degrees Celsius kg/mol. The molar mass of GLUCOSE is 180 g/mol. The boiling point of water is 100 degrees Celsius. The equation for boiling-point elevation is delta T = mKb. |
