WebSee Answer. Question: Question 18 5 pts When a non-volatile solute is added to a solvent, the melting point of the solution will be higher than the melting point of the pure solvent. O the vapor pressure of the solution will be higher than the vapor pressure of the pure solvent. no changes will be observed because melting point and boiling ... WebBoiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases. An example of this would be the addition of ...
WebMay 6, 2024 · Updated on May 06, 2024. 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. A common example of boiling point elevation can be observed by adding salt to water. WebBecause changes in the boiling point of the solvent (T BP) ... Values of k f and k b as well as the freezing points and boiling points for a number of pure solvents are given in the tables below.
