Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

Frothing milk involves a process that introduces air into the chemical properties of milk to create the light and airy product of frothed or foamed milk. [3] Milk is made up of proteins, fats, and carbohydrates. The fats and proteins determine the thickness and the flavor of the foam.
A blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or phase transition, such as polymers, plastics, and metals. [1]
The term reflux [1] [3] [4] is very widely used in industries that utilize large-scale distillation columns and fractionators such as petroleum refineries, petrochemical and chemical plants, and natural gas processing plants.
Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
Steam distillation is a means of purifying fatty acids, e.g. from tall oils. [9] Steam distillation is sometimes used in the chemical laboratory. Illustrative is a classic preparation of bromobiphenyl where steam distillation is used to first remove the excess benzene and subsequently to purifiy the brominated product. [10]
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".
