Frequently Asked Questions
What causes boiling point elevation?
Dissolved solute particles disrupt the solvent ability to form vapor at the surface, requiring a higher temperature to reach the vapor pressure needed for boiling — a colligative property that depends on particle concentration, not solute identity.
What is the ebullioscopic constant for water?
Water has an ebullioscopic constant of approximately 0.512 degrees Celsius kilogram per mole, the default value used here — other solvents have different constants based on their molecular properties.
Does this work for solutes that dissociate, like salts?
For dissociating solutes, the effective molality should be multiplied by the number of particles produced per formula unit, similar to the dissociation factor used in osmolarity calculations, for an accurate result.
