Hydroxide is a diatomic anion consisting of one atom of oxygen and hydrogen bonded together by a covalent bond, with chemical formula as OH- and carries negatively charged ion. It functions as a nucleophile, a ligand, a catalyst, and a base.
Ion of a metal is usually the positively charged part of the compound, for example, aluminum, magnesium or sodium, and might be in the organic group. The inorganic hydroxides consist of alkali and alkali earth metals are important industrial alkalis like calcium hydroxide and sodium hydroxide.
The hydroxide attached to electropositive can ionize itself and liberate hydrogen cation (H+) converting the parent compound to an acid. On the other hand, many of inorganic substance having the word hydroxide in their name are the covalent compound containing hydroxyl groups but not the ionic compounds of hydroxide ion.
Due to the self-ionization reaction, the hydroxide ion is a natural part of water.
While, the equilibrium constant of this reaction is defined as
The solutions of sodium hydroxide are widely used in the manufacture of paper, pulp, textiles, soaps, detergents, drinking water and drain cleaner. It is also known as caustic soda and lye. The primary method of manufacturing by the process of chlor-alkali.
The solution that contains hydroxide ion is obtained when weak acid salt is dissolved in water. The sodium carbonate is used as an alkali by the behaviour of the hydrolysis reaction.
Bauxite is the primary or through which the metal is the manufacturer and is a basic of the hydroxide of aluminum. Similarly, lepidocrocite
Apart from Sodium hydroxide NaOH and potassium hydroxide KOH, the hydroxides of other alkali metals are also useful. The lithium hydroxide
Alkaline Earth Metals
The Beryllium hydroxide
Boron Group Elements
The boric acid is the simplest hydroxide of boron
Carbon Group Elements
The carbon forms complex hydroxides. The hypothetical compound
While, the carbon dioxide is also known as carbonic anhydride, which means that it is formed by dehydration of carbonic acid
Other Main-Group Elements
The other main-group elements of hydroxide in inorganic hydroxides are sulfuric acid, xenic acid, telluric acid, phosphoric acid, ortho-periodic acid and phosphorous acid.
Hydroxide in Organic Reactions
Sodium hydroxide and potassium hydroxide are the two popular substance in organic chemistry.
The hydroxide ions in organic reactions act as a base catalyst. It abstracts a proton from a weak acid and the common substance for proton abstraction are carbon acids, amines phenols, and alcohols.
The hydroxide ion in nucleophilic is intermediate between the amido ion
