How does the Boiling Point Elevation work?

ΔTb = i × Kb × m Then: Kb(water) = 0.512 °C·kg/mol Then: Higher solute concentration and ionic dissociation → larger elevation.

Can you give an example of how to use the Boiling Point Elevation?

Example: Input 0.5 mol sucrose in 1 kg water · i=1 · Kb=0.512 gives a result of ΔTb = 0.256°C → boils at 100.256°C (1×0.512×0.5=0.256°C).

Is the Boiling Point Elevation free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

Boiling point elevation is a colligative property: dissolving a solute raises the boiling point of the solvent. ΔTb = i × Kb × m. For water, Kb = 0.512 °C·kg/mol.

Did You Know?

Pasta water salted at restaurant levels (~1%) raises the boiling point by only 0.05°C — essentially irrelevant for cooking speed. Salt is added for flavour, not temperature.
