Hydroxide definition is - the monovalent anion OH— consisting of one atom of hydrogen and one of oxygen —called also hydroxide ion. A group of bases containing hydroxide are called hydroxide bases. This led naturally to the simple definition that acids…
An estimated 700,000 to 800,000 tonnes were produced in 2005. Hydrolyze Definition To hydrolyze a bond is to break it apart with water.

Hydroxide Definition Hydroxide is a negatively charged ion comprised of oxygen and hydrogen atom bonded covalently with each other. Specific examples include sodium hydroxide, nitric acid, and hydrogen peroxide. Une pierre précieuse peut être un corps élémentaire comme le diamant, un oxyde comme le rubis, un hydroxyde comme l'opale ( Metta , Pierres préc., 1960 , p. 20). A corrosive substance is defined as a material capable of damaging or destroying other substances on contact via a chemical reaction. The hydroxides are regarded as compounds of hydroxyl, united usually with basic element or radical; as, calcium hydroxide ethyl hydroxide.

It is not intended to provide medical, legal, or any other professional advice. The sulfuric acid formula, H 2 SO 4, indicates the presence of a sulfur atom surrounded by two hydroxide compounds and two oxygen atoms. Other articles where Hydroxide ion is discussed: acid–base reaction: Hydrogen and hydroxide ions: …associated with the presence of hydroxide ions (OH−) in aqueous solution, and the neutralization of acids by bases could be explained in terms of the reaction of these two ions to give the neutral molecule water (H+ + OH− → H2O).


The process typically requires the use of a catalyst, since hydrogenation only occurs spontaneously at …

Hydroxide (Science: chemistry) a hydrate; a substance containing hydrogen and oxygen, made by combining water with an oxide, and yielding water by elimination.

Sodium hydroxide is toxic and strongly alkaline and is used to make chemicals and soaps and to refine petroleum. The hydroxide ions can combine with H(+) to create water. From the Greek words hydro and lysis, or "water break", hydrolyze is literally just that.

So, the more hydroxide ions a molecule releases (or … Free learning resources for students covering all major areas of biology.

Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. The positively charged portion of the compound usually is the ion of a metal (e.g., sodium, magnesium, or aluminum), although it may be an organic group (e.g., guanidinium or tetramethylammonium). Hydroxide definition, a chemical compound containing the hydroxyl group.

Hydroxide ion in the largest biology dictionary online.

Hydroxide is a chemical compound containing one or more hydroxyl radicals (OH). Other names are sulphine acid, battery acid, and hydrogen sulfate. Definition.

Origin: Hydro-, 2 – oxide. Because the hydrogen ions are used, the number of hydrogen ions in the solution decreases, making the solution less acidic and therefore more basic. chim., t. 1, 1929, p. 321).

Water (or H2O) breaks into two parts: a positive hydrogen, H+, and a negative hydroxide, (OH)-. It normally attached with a … See more. Hydroxide is a polyatomic ion consisting of oxygen and hydrogen: OH− It has a charge of −1.

A hydroxyl group is a pair of atoms that is commonly found in organic compounds, such as sugars and alcohols.

Calcium hydroxide has been used famously in the past for induction of apical barrier, having success rates ranging from 79%-96%.6 However, being a long history of use in apical closure procedures, there are many drawbacks associated with the use of calcium hydroxide for apexification procedure. What made you want to look up hydroxide? Hydroxide bases will dissociate into a cation and one or more hydroxide ions in water, making the solution basic. Hydroxide is one of the simplest of the polyatomic ions.

It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids. Sulfuric acid (sulphuric acid) is a corrosive mineral acid with an oily, glassy appearance that gave it its earlier name of oil of vitriol.
