Hydroxide
OH⁻
Hydroxide is a compound consisting of one oxygen atom and one hydrogen atom. The chemical formula for hydroxide is OH-. It is one of the simplest and most commonly occurring polyatomic ions in chemistry. Hydroxide plays an important role in many chemical reactions, for example, in acid-base reactions, where it neutralizes acids and forms water.
Hydroxide is formed when a hydroxyl group (-OH) is negatively charged. This can occur when hydrogen atoms from a molecule of water are lost, or when certain salts dissolve in water. For example, when sodium hydroxide (NaOH) dissolves in water, it dissociates into Na+ and OH- ions, creating a basic (alkaline) solution.
Hydroxide ions play a crucial role in living organisms. They are important components of biological molecules such as proteins, nucleic acids, and carbohydrates. Hydroxide is also involved in regulating the pH of the body’s internal environment. Additionally, it is used in many industrial processes, such as the production of paper, textiles, and various chemicals.
Overall, Hydroxide is an important chemical compound that has a wide range of applications across multiple industries and in biological systems.
