ARTICLES RELATED TO Solvent

Solvent: Encyclopedia - Solvent

A solvent is a liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution. The most common solvent in everyday life is water. The term organic solvent refers to most other solvents that are organic compounds and contain carbon atoms. Solvents usually have a low boiling point and evaporate easily or can be removed by distillation, thereby leaving the dissolved substance behind. Solvents should therefore not react chemically with the dissolved compounds — they have to be inert. Solvents can also be ...

Solvent: Encyclopedia - Protic solvent In chemistry any solvent that carries hydrogen attached to oxygen as in a hydroxyl group, nitrogen as in a amine group, or, more generally, any molecular solvent which contains dissociable H+, such as hydrogen fluoride, is called a protic solvent. The molecules of such solvents can donate an H+ (proton). Common characteristics: solvents display hydrogen bonding solvents are acidic solvents are able to stabilise ions cations by unshared free electron pairs anions by hydrogen bonding Examples are water, methanol, ...

Solvent: Encyclopedia II - Solvent - Safety

Most organic solvents are flammable or highly flammable, depending on their volatility. Exceptions are some chlorinated solvents like methylene chloride and chloroform. Mixtures of solvent vapors and air can explode. Solvent vapors are heavier than air, they will sink to the bottom and can travel large distances nearly undiluted. Solvent vapors can also form in supposedly empty drums and cans, posing a flash fire hazard; hence empty containers of volatile solvents shou ...

Solvent: Encyclopedia - Ammonia

Ammonia is a compound of nitrogen and hydrogen with the formula NH3. At standard temperature and pressure ammonia is a gas. It is toxic and corrosive to some materials, and has a characteristic pungent odor. An ammonia molecule is not flat, but has the shape of a compressed tetrahedron known as a trigonal pyramid, as would be expected from VSEPR theory. This shape gives the molecule an overall dipole moment and makes it polar so that ammonia very readily dissolves in water. The nitrogen atom in the molecule has a lon ...

This article is in need of attention. You can help Wikipedia by editing it into a better article. Please also consider changing this notice to be more specific. Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapour pressures under normal conditions to significantly vaporize and enter the atmosphere. (The term VOC is also occasionally used as an abbreviation, especially in biological contexts, for "volatile organic carbon".) A wide range of ...

Solvent: Encyclopedia - Acetic acid

Acetic acid, also known as ethanoic acid, is an organic chemical compound best recognized for giving vinegar its sour taste and pungent smell. Pure water-free acetic acid is a colourless hygroscopic liquid (that is, it readily absorbs water) that freezes below 16.7 °C (62 °F) to a colourless crystalline solid. Acetic acid is corrosive, and its vapour is irritating to eyes and nose, although it is a weak acid based ...

Solvent: Encyclopedia - Water molecule

Water has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. It is in dynamic equilibrium between the liquid and solid states at standard temperature and pressure. At room temperature, it is a nearly colorless, tasteless, and odorless liquid. It is often referred to in the sciences as the universal solvent and the only pure substance found naturally in all three states of matter. Water molecule - Forms of water. See ...

Solvent: Encyclopedia - White spirit

White spirit, also known as Stoddard solvent is a paraffin-derived clear, transparent liquid which is a common organic solvent used in painting and decorating. It is a mixture of saturated aliphatic and alicyclic C7 to C12 hydrocarbons with a maximum content of 25% of C7 to C12 alkyl aromatic hydrocarbons. White spirit is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products. In western Europ ...

Swelling. In medicine, swelling is the enlargement of organs caused by accumulation of excess fluid in tissues, called edema. In engineering, swelling is the increase of volume of material, usually due to absorption of a solvent (common for polymers, or by structural changes caused by neutron radiation.

Solvent: Encyclopedia - Wood stain

Wood stain is a type of paint that is very "thin," that is, low in viscosity, and formulated so that the pigment penetrates the surface rather than remaining in a film on top of the surface. Stain is predominantly pigment or dye and solvent with little binder, designed primarily to add color without providing a surface coating. Other related archivesdye, paint, pigment, solvent

Solvent: Encyclopedia - Wet alife

Wet alife refers to artificial life created in water (or other solvent) based chemical substrates .

Solvent: Encyclopedia - Concentrate

A concentrate is a form of substance which has had the majority of its base component, or solvent, removed. Typically this will be the removal of water from a solution or suspension such as the removal of water from fruit juice. The benefit of producing a concentrate is that of a reduction in weight and volume for transportation as the concentrate can be re-constituted at the time of usage by the addition of the solvent. See also. concentration ...

Solvent: Encyclopedia - Inhalant

Inhalants are a chemically diverse group of psychoactive substances composed of organic solvents and volatile substances commonly found in more than 1000 common household products, such as glues, hair spray, air fresheners, gasoline, lighter fluid, and paint. The practice of inhaling such substances is sometimes colloquially referred to as solvent abuse or huffing. Solvents are some of the most dangerous substances used recreationally, and can cause serious damage to the brain and central nervous system, an ...

Solvent: Encyclopedia - Concentration

In chemistry, concentration is the measure of how much of a given substance there is mixed with another substance. This can apply to any sort of chemical mixture, but most frequently is used in relation to solutions, where it refers to the amount of solute dissolved in a solvent. To concentrate a solution, one must add more solute, or reduce the amount of solvent (for instance, by selective evaporation). By contrast, to dilute a solution, one must add more solvent, or reduce the amount of solute. ...

Solvent: Encyclopedia - Absolutes

Absolutes are similar to essential oils and are used in aromatherapy. The difference is that where essential oils are created through a process of distillation absolutes are extracted with the use of chemical solvents. Absolutes may be more concentrated than essential oils but can sometimes contain traces of the solvents used. This is in stark contrast to the idea of purity generally associated with aromatherapy. Absolutes are more commonly used in perfumery applications, since, if both an essential oil and an absolute o ...

Solvent: Encyclopedia - Alkahest

Alkahest (or alcahest) is a hypothetical universal solvent, having the power to dissolve every other substance, including gold. It was much sought after by alchemists for its invaluable medicinal qualities. The name is believed to have been invented by Paracelsus (1493–1541), who modelled it on similar words taken from Arabic, such as ‘alkali’. Paracelsus' own recipe was based on caustic lime, alcohol, and carbonate of potash. In fact a universal solvent does not, and cannot, exist. The closest is likely to be aqua regia — or, depending ...
