- Boiling point of a binary mixture
- C-AV-26/EV
  Details
  The boiling point diagram shows the boiling points of a binary mixture according to the liquid vapour equilibrium of the mixture at constant pressure. Through this […]
- Discover
- Boiling-point elevation in a solution
- F-BP/EV
  Details
  The boiling point of a solution is always higher than that of pure solvent. A special apparatus enables to determine how the difference of temperature (boiling-point […]

- Charge transport of liquids
- C-AV-34/EV
  Details
  A difference in potential between two electrodes in a liquid leads to a flow of current in the liquid. This current depends on the potential drop […]

- Determination of the enthalpy of fusion of a pure substance
- C-AV-18/EV
  Details
  When a solid melts, energy is required to break the crystal lattice. A substance whose melting point lies slightly below the ambient temperature is first cooled […]
- Discover
- Determination of the enthalpy of neutralisation
- C-AV-17/EV
  Details
  When a strong acid is neutralised with a strong base in a diluted solution, the same amount of heat is always released. If the reaction takes […]
