Boiling Point Elevation
Phenomenon where adding a solute to a solvent increases the boiling point of the solution. Normal Boiling Point
The boiling point of a pure solvent before any solute is added. Boiling Point of Solution
The boiling point of a solvent after a solute has been added. ΔTb
The change in boiling point due to the addition of a solute. Van't Hoff Factor
A factor representing the number of particles a solute forms in solution. Kb
The boiling point elevation constant of a solvent, measured in °C/m. Molality
Concentration of a solution expressed as moles of solute per kilogram of solvent. Colligative Properties
Properties of solutions that depend on the number of solute particles, not their identity. Covalent Compound
A compound with a Van't Hoff factor of 1, typically non-volatile and non-ionic. Non-volatile
A substance that does not readily evaporate into a gas under existing conditions. Non-ionic
A compound that does not dissociate into ions in solution. Electrolyte
A substance that dissociates into ions in solution, affecting the Van't Hoff factor. Water
A common solvent with a Kb value of 0.51 °C/m used in boiling point elevation. Benzene
A solvent with a Kb value of 2.53 °C/m used in boiling point elevation. Chloroform
A solvent with a Kb value of 3.60 °C/m used in boiling point elevation.
