colligative
21Van 't Hoff factor — In physical chemistry, the van t Hoff factor i is the number of moles of solute actually in solution per mole of solid solute added. Equivalently, i refers to the ratio of true molecular mass to calculated molecular methods by colligative methods …
22Osmosis — is the movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, aiming to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a phy …
23Osmotic pressure — Morse equation redirects here. For the potential energy of a diatomic molecule, see Morse potential. For the functions in differential topology, see Morse theory. Osmotic pressure on red blood cells Osmotic pressure is the pressure which needs to …
24Activity (chemistry) — In chemical thermodynamics, activity (symbol a) is a measure of the “effective concentration” of a species in a mixture, meaning that the species chemical potential depends on the activity of a real solution in the same way that it would depend… …
25Antifreeze protein — Antifreeze proteins (AFPs) or ice structuring proteins (ISPs) refer to a class of polypeptides produced by certain vertebrates, plants, fungi and bacteria that permit their survival in subzero environments. AFPs bind to small ice crystals to… …
26Antifreeze — is a freeze preventive used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. The purpose of antifreeze is to prevent a rigid enclosure from undergoing catastrophic deformation due …
27Freezing-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… …
28Boiling-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… …
29Colligativité — Propriété colligative Les propriétés colligatives des solutions chimiques sont des propriétés qui dépendent uniquement du nombre et non de la nature des particules de solutés dans une solution. Les propriétés colligatives peuvent être employées… …
30Outline of chemistry — The following outline is provided as an overview of and topical guide to chemistry: Chemistry – science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties,… …
