Arrhenius base is a substance that produces hydroxide ions when dissolved in an aqueous solution.

Hydroxide ions are used in most compounds as chemical bases and are involved in neutralisation and numerous acid-base reactions. Here is an example:ĬuSO4 + 2NaOH → Cu(OH)2 + Na2SO4 Hydroxide ions as a chemical base To get a metal’s hydroxide that does not react directly with water, an exchange reaction or metathesis takes place. To get sodium hydroxide, add metallic sodium into water. Let us look at the formation of sodium hydroxide. The hydration reaction of rare Earth metals and alkali metals is the most prevalent method of hydroxide formation. Bauxite and limonite are mineral ores that are examples of hydroxides. Some of the common hydroxide-ion compounds are ammonium hydroxide, potassium hydroxide, and sodium hydroxide. Hydroxide bases are a group of bases consisting of hydroxide ions. It is a polyatomic ion with a negative OH charge consisting of hydrogen and oxygen. Many useful chemicals and chemical processes have hydroxide ions and hydroxides – take, for example, potassium hydroxide used in agriculture and sodium hydroxide used in different industries as a strong base. Hydroxide ions and hydroxides are relatively common in nature. Hydroxide ions form different salts and some of the salts segregate in an aqueous solution. This bond carries a negative charge and is one of the simplest polyatomic ions with a -1 charge. Hydroxide ion bonds are held together by a single covalent bond. Hydroxide ions consist of hydrogen and oxygen. In chemistry, Hydroxide is the most common name for the diatomic anion, OH−.
