Formation of Hydroxide
A chemical substance that contains the hydroxyl ion (OH–) is referred to as an oxide. A base reacting with water or another acid usually forms hydroxides. As a negatively charged species, the hydroxyl ion forms hydroxide compounds when it combines with positively charged metals or other cations.
Here are two typical processes by which hydroxides might form:
Hydroxides of Metals
Metal hydroxides are created when metals react with water, particularly alkali and alkaline earth metals. For instance:
Metal (M) + Water (H2O) → Metal Hydroxide (M(OH)2) + Hydrogen (H2O )
Depending on which metal is involved in the process, a certain hydroxide will produced.
Dissociation of Base
Substances known as bases have the ability to contribute electron pairs or take protons (H+). A base and water can react to produce hydroxide ions:
Base + Water → Hydroxide Ion + Conjugate Acid
To form hydroxide ions, for instance, ammonia (NH3) can combine with water.
NH3 + H2O → NH4+ + OH–
Hydroxide Ion
Hydroxide Ion is a diatomic anion whose chemical formula is OH−. This negatively charged ion is made up of a hydrogen and an oxygen atom which are bonded together by a covalent bond. Hydroxide is also known as a hydroxide radical. This is a diatomic compound with valency -1.
In this article, we will have a complete explanation of Hydroxide ions, and will also learn about their formation, structure, properties, uses, and more.
