  2. Saponification - Wikipedia

    en.wikipedia.org/wiki/Saponification

    Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali.Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis.

  3. Saponification value - Wikipedia

    en.wikipedia.org/wiki/Saponification_value

    [1] [2] [3] It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample in form of triglycerides. The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa.

  4. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Since water is frequently used as the solvent in experiments, the word solution refers to an aqueous solution, unless the solvent is specified. [3] [4] A non-aqueous solution is a solution in which the solvent is a liquid, but is ...

  5. Glossary of chemistry terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemistry_terms

    This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...

  6. Solution (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Solution_(chemistry)

    Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.

  7. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base.The term is used in many contexts and for many classes of chemical compounds.

  8. Chemical affinity - Wikipedia

    en.wikipedia.org/wiki/Chemical_affinity

    In chemical physics and physical chemistry, chemical affinity is the electronic property by which dissimilar chemical species are capable of forming chemical compounds. [1] Chemical affinity can also refer to the tendency of an atom or compound to combine by chemical reaction with atoms or compounds of unlike composition.

  9. Precipitation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Precipitation_(chemistry)

    [1] [2] The solid formed is called the precipitate. [3] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. [4] The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant.
