Boiling-point elevation — describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non volatile solute, such as a… … Wikipedia
Molar mass — Formula mass redirects here. It is not to be confused with Mass formula. Molar mass, symbol M,[1] is a physical property of a given substance (chemical element or chemical compound), namely its mass per amount of substance.[2] The base SI unit… … Wikipedia
Freezing-point depression — This article deals with melting and freezing point depression due to mixture of another compound. For depression due to small particle size, see melting point depression. Freezing point depression describes the phenomenon in which the freezing… … Wikipedia
Colligative properties — are properties of solutions that depend on the number of molecules in a given volume of solvent and not on the properties/identity (e.g. size or mass) of the molecules.[1] Colligative properties include: relative lowering of vapor pressure;… … Wikipedia

Osmolarity — This article is about osmolarity. For the osmole unit, see Osmole (unit). Osmolarity is the measure of solute concentration, defined as the number of osmoles (Osm) of solute per litre (L) of solution (osmol/L or Osm/L). The osmolarity of a… … Wikipedia
Ebullioscopic constant — In thermodynamics, the ebullioscopic constant, Kb, allows one to relate molality to boiling point elevation. It is the ratio of the latter to the former: riangle T = K b * mThrough the procedure called ebullioscopy, a known constant can be used… … Wikipedia
