In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. If the attractive forces between the solvent and solute particles are greater than the attractive forces holding the solute particles together, the ...
Chromatography – a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. Eluent (sometimes spelled eluant) – the solvent or solvent fixure used in elution chromatography and is synonymous with mobile phase.
An electrolyte is a medium containing ions that are electrically conductive through the movement of those ions, but not conducting electrons. [ 1][ 2][ 3] [clarification needed (see talk)] This includes most soluble salts, acids, and bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into cations and anions ...
Vortex mixer, static mixer. A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel ...
Laboratory flask. In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. [1] Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight ...
Precipitation (chemistry) Principle of chemical precipitation in aqueous solution. In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [ 1][ 2] The solid formed is called the precipitate. [ 3] In case of an inorganic chemical reaction leading to precipitation, the chemical ...
There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for ...
Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. Laboratory-grown (LGD), also called lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is created through geological processes ...
