Boiling-point elevation (Landsberger) template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
Landsberger apparatus: steam generator with safety tube, vapour bubbled through the solution in a graduated inner tube with a thermometer, inside a vapour jacket. University physical; Indian BSc labs.
What the template shows
- Heat a solution with solvent vapour and read how far its boiling point rises
- Safety tube
- Open to the air; foot under the water
- Steam generator
- Pure solvent (here water) boiled briskly with anti-bumping granules
- Heating mantle
- First find the boiling point of the pure solvent the same way; read it when steady
- Vapour jacket
- Vapour leaving the inner tube keeps it hot. ΔTb = Kb·b; Kb(water) = 0.51 K kg mol⁻¹
- Graduated inner tube
- Weighed solute in a few mL of solvent; read the volume at once after the temperature
- Rose head
- Vapour bubbles through and heats the solution to its boiling point without superheating
- Or to waste: the excess vapour escapes here
- Reaction setup
Drawn with 13 shapes – every one editable in MolDraw.
