Separation of substances in solution by the difference in their rates of diffusion through a semipermeable, membrane.
The movement of molecules or other particles in solution from an area of greater concentration to an area of lesser concentration until uniform concentration is reached.
A solution containing a relatively small amount of solute.
A solution containing solutes capable of conducting electricity.
A mixture of two insoluble liquids, one being dispersed throughout the other in small droplets.
An organic catalyst produced by living cells and capable of autolytic decomposition.
Colorless, strong-smelling gas that when used in solution is a powerful preservative and disinfectant; a potential occupational carcinogen; often abbreviated HCHO (line formula)
A liquid mixture of formaldehyde and water; 37% formaldehyde by weight and 40% formaldehyde by volume.
A specific atom or group of atoms that is attached to a carbon atom in an organic compound and that imparts an identifiable chemical behavior to the compound.
A univalent radical and the functional group of the basic compounds in inorganic chemistry and the alcohols in organic chemistry.
Absorbing moisture readily.
A solution having a greater concentration of dissolved solute than the solution to which it is compared.
A solution having a lesser concentration of dissolved solute than the solution to which it is compared.
A solution of two mutually insoluble liquids.
The strength of arterial fluids indicated by the number of grams of pure formaldehyde gas dissolved in 100 ml of water. Index usually refers to a percentage.
That branch of chemistry that studies the properties and reactions of elements, excluding organic or certain carbon-containing compounds.
A solution having an equal concentration of dissolved solute to that of a standard of reference.
Liquid compound form of formaldehyde; formed when water and formaldehyde react; different from formalin, which is simply a physical mixture.
A solution of two mutually soluble liquids.
A combination of two or more substances not chemically united and in no definite proportion by mass.
A solution containing solutes incapable of conducting electricity.
That branch of chemistry that deals with certain carbon containing compounds.
The passage of solvent from a solution of lesser to one of greater solute concentration when the two solutions are separated by a semipermeable membrane.
The force being exerted by the dilute solution against the concentrated solution during osmosis.
The solid (powder) form of formaldehyde.
The number of grams of a solute in one hundred grams of solution; when the solute is formaldehyde, the percentage is referred to as index.
The linking together of monomer or basic chemical units to form a polymer molecule; e.g. the linking of HCHO molecules to form paraformaldehyde.
Organic compound found in plants and animals; can be broken down into amino acids.
Decomposition of proteins.
Decomposition of proteins by the action of enzymes from anaerobic bacteria.
A comparison between the number of parts of the solute and total number of parts in the solution (solute + solvent).
A solution containing all of the solute the solvent is able to hold at a certain temperature and pressure.
The measure of how well two substances mix; or, the amount of solute needed to produce a saturated solution in a given amount of solvent.
Term that describes a solute that can be readily dissolved by or absorbed into a solvent.
The substance that is dissolved in a solution.
A homogeneous mixture of one or more substances (solutes) dissolved in a sufficient quantity of solvent.
The process of forming a solution or the process of dissolving.
A substance that does the dissolving in a solution; the component of a solution present in the greater amount; a liquid holding another substance in solution.
A solution containing more solute than it could normally hold under ordinary circumstances (i.e. normal pressure and temperature).
An inorganic mixture of a solute and a solvent in which the size of the solute particles is greater than 100 nanometers; particles of solute do NOT pass through filters OR membranes.
A solution in which alcohol is the solvent.
The use of pressure to force colloidal products across/through the cell membrane.
A solution containing less of the solute than can be held in solution by the solvent.
A compound formed when formaldehyde reacts with ammonia; this reaction neutralizes the formaldehyde and creates a risk of under-embalming.
Liquid that serves as a solvent for the numerous ingredients that are incorporated into embalming fluids.
