Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar. Consequently, the molecule has a large dipole moment with a negative partial charge (δ−) at the chlorine atom ...
Infobox references. 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. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: feq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c (H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.
Hydrochloride. 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.
Dorzolamide. Dorzolamide, sold under the brand name Trusopt among others, is a medication used to treat high pressure inside the eye, including in cases of glaucoma. [ 3] It is used as an eye drop. [ 3] Effects begin within three hours and last for at least eight hours. [ 3]
HCLTech. [ 5] HCL Technologies Limited, doing business as HCLTech, [ 6] is an Indian multinational information technology (IT) consulting company headquartered in Noida. Founded by Shiv Nadar, it was spun out in 1991 when HCL entered into the software services business. The company has offices in 60 countries and over 220,000 employees.
The hydrogen electrode is based on the redox half cell corresponding to the reduction of two hydrated protons, 2H+(aq), into one gaseous hydrogen molecule, H2 (g). General equation for a reduction reaction: The reaction quotient ( Qr) of the half-reaction is the ratio between the chemical activities ( a) of the reduced form (the reductant, ared ...
