Calculate boiling point elevation instantly using our free calculator. Enter molality and ebullioscopic constant to determine how solutes raise boiling temperature. Perfect for chemistry students and professionals.
Calculate the elevation in boiling point of a solution based on the molality of the solute and the ebullioscopic constant of the solvent.
The concentration of solute in moles per kilogram of solvent.
A property of the solvent that relates the molality to the boiling point elevation.
Select a common solvent to automatically set its ebullioscopic constant.
ΔTb = 0.5120 × 1.0000
ΔTb = 0.0000 °C
Boiling point elevation is a colligative property that occurs when a non-volatile solute is added to a pure solvent. The presence of the solute causes the boiling point of the solution to be higher than that of the pure solvent.
The formula ΔTb = Kb × m relates the elevation in boiling point (ΔTb) to the molality of the solution (m) and the ebullioscopic constant (Kb) of the solvent.
Common ebullioscopic constants: Water (0.512 °C·kg/mol), Ethanol (1.22 °C·kg/mol), Benzene (2.53 °C·kg/mol), Acetic acid (3.07 °C·kg/mol).
