In a scientific sense, a chemical change could be a technique or suggests that of somehow dynamic one or additional chemicals or chemical compounds. Such a chemical change will occur by itself or be caused by an outdoor force and involves a chemical action of some kind. In AN “engineering” sense, a chemical change could be a technique meant to be employed in producing or on AN industrial scale (see Industrial process) to vary the composition of chemical(s) or material(s), sometimes mistreatment technology similar or associated with that employed in chemical plants or the industry.
Neither of those definitions squares measures precise within the sense that one will perpetually tell definitively what’s a chemical change and what’s not; they’re sensible definitions. there’s an additionally important overlap in these 2 definition variations. attributable to the inexactitude of the definition, chemists and alternative scientists use the term “chemical process” solely in a general sense or within the engineering sense. However, within the “process (engineering)” sense, the term “chemical process” is employed extensively. the remainder of the article can cowl the engineering sort of chemical processes.

SOME CHEMICAL PROCESS
- OXIDATION
Redox may be a sort of chemical change during which the chemical reaction states of atoms square measure modified. oxidation-reduction reactions square measure characterized by the particular or formal transfer of electrons between chemical species, most frequently with one species (the reducing agent) undergoing chemical reaction (losing electrons) whereas another species (the oxidizing agent) undergoes reduction (gains electrons). The chemical species from which the lepton is removed is claimed to possess been changed, whereas the chemical species to that the lepton is another is claimed to possess been reduced. - HYDROGENATION
Hydrogenation may be a chemical change between molecular part|element|gas} (H2) and another compound or element, sometimes within the presence of a catalyst like nickel, metallic element, or Pt. the method is usually used to cut back or saturate organic compounds. chemical change usually constitutes the addition of pairs of element atoms to a molecule, usually Associate in Nursing olefine. Catalysts square measure needed for the reaction to be usable; non-catalytic chemical change takes place solely at terribly high temperatures. the chemical change reduces double and triple bonds in hydrocarbons. - DEHYDROGENATION
Dehydrogenation is the chemical change that involves the removal of the element, sometimes from Associate in Nursing organic molecule. it’s the reverse of chemical change. Dehydrogenation is very important, each as a helpful reaction and a heavy downside. At its simplest, it’s a helpful approach to changing alkanes, that square measure comparatively inert and so low-valued, to olefins, that square measure reactive and so a lot of value. Alkenes square measure precursors to aldehydes, alcohols, polymers, and aromatics. As a problematic reaction, the fouling and inactivation of the many catalysts arise via coking, that is that the dehydrogenative chemical action of organic substrates.

FAQs
What is dehydration reaction?
A dehydration reaction may be a chemical change that involves the loss of water from the reacting molecule or particle. Dehydration reactions square measure common processes, the reverse of an association reaction.
What is the association process?
An association reaction may be a chemical change during which a substance combines with water. In chemistry, water is another Associate in Nursing unsaturated substrate, which is typically Associate in Nursing olefine or Associate in Nursing ethyne. this kind of reaction is utilized industrially to supply plant products, alcohol, and butane-2-ol.
What is Hydrolysis?
Hydrolysis is any chemical change during which a molecule of water breaks one or a lot of chemical bonds. The term is employed loosely for substitution, elimination, and association reactions during which water is the nucleophile.
