1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1]It is typically employed in the 4.0-6.0 pH range.
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases.
Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. [25] Hydrogen chloride, not hydrochloric acid, is used more widely in industrial organic chemistry, e.g. for vinyl chloride and dichloroethane. [8]
The reaction between hydrochloric acid and calcium carbonate (limestone or chalk) is shown below: CaCO 3 + 2 HCl → CaCl 2 + H 2 CO 3. The carbonic acid (H 2 CO 3) then decomposes to water and CO 2: H 2 CO 3 → CO 2 + H 2 O. Such reactions are accompanied by foaming or bubbling, or both, as the gas is released.
Arsenic trichloride can be prepared by the reaction of arsenic oxide and sulfur monochloride. This method requires simple apparatus and proceeds efficiently: [8] 2 As 2 O 3 + 6 S 2 Cl 2 → 4 AsCl 3 + 3 SO 2 + 9 S. A convenient laboratory method is refluxing arsenic(III) oxide with thionyl chloride: [9] 2 As 2 O 3 + 3 SOCl 2 → 2 AsCl 3 + 3 SO 2
The equilibria reactions between these species result in the buffering of seawater in terms of the concentrations of hydrogen ions present. [8] The following chemical reactions exhibit the dissolution of carbon dioxide in seawater and its subsequent reaction with water: CO 2 (g) + H 2 O(l) ⥨ H 2 CO 3 (aq) H 2 CO 3 (aq) ⥨ HCO 3 − (aq) + H ...
In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
