What Is Decanting? The term 'decant' is usually associated with wine. Decanting is also a chemical laboratory process used to separate mixtures. Answer: Decanting is a process to separate mixtures. Decanting is just allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity. This process can be slow and tedious without the aid of a centrifuge.

Diethylene glycol Diethylene glycol is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century.

What's the difference between a reagent and reactant? A reactant is a substance that is being used up or consumed in a chemical reaction. It is needed in large amount as compaed to reagent. A reagent is something which is used to initiate a reaction and aids to carry out it and it is also consumed in a reaction, unlikely to catalysts which are not consumed in a reaction.

- Ethylene glycol (IUPAC name: ethane-1,2-diol; Chemical formula C2H6O2) is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure … form, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is toxic, and ingestion can result in death.

- Although the terms reactant and reagent are often used interchangeably, a reactant is more specifically a substance that is consumed in the course of a chemical reaction. Solvents, although they are involved in the reaction, are usually not referred to as reactants.hen purchasing or preparing chemicals, reagent-grade describes chemical substances of sufficient purity for use in chemical analysis, chemical reactions or physical testing. Purity standards for reagents are set by organizations such as ASTM International or the American Chemical Society.

- Freebase(0.00 / 0 votes)Rate this definition: Surfactant. Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

Reactant Definition and Examples Examples of Reactants. A general reaction may be given by the equation: A + B → C. In this example, A and B are the reactants and C is the product. There do not have to be multiple reactants in a reaction, however. In a decomposition reaction, such as: C → A + B. C is the reactant, while A and B are the products. You can tell the reactants because they are at the tail of the arrow, which points toward the products. H2 (hydrogen gas) and O2 (oxygen gas) are reactants in the reaction that forms liquid water: 2 H2(g) + O2(g) → 2 H2O(l).

- An example of decanter. Decantation is a process for the separation of mixtures, by removing a layer of liquid, generally one from which a precipitate has settled. The purpose may be either to produce a clean decant, or to remove undesired liquid from the precipitate (or other layers).ecantation is a process for the separation of mixtures, by removing a layer of liquid, generally one from which a precipitate has settled.
