Hydroxide ion is a diatomic anion with the chemical formula OH-. It consists of one oxygen atom covalently bonded to one hydrogen atom. The oxygen atom carries a net negative charge, making it a negatively charged ion. Hydroxide ions are a fundamental component of bases, which are substances that increase the concentration of hydroxide ions in aqueous solutions. In water, bases dissociate to release hydroxide ions, thereby increasing the pH of the solution. Conversely, acids react with bases, neutralizing the hydroxide ions and decreasing the pH.

The hydroxide ion plays a crucial role in numerous chemical and biological processes. It is involved in acid-base reactions, saponification (the process of making soap), and the hydrolysis of many organic compounds. In biological systems, hydroxide ions are essential for maintaining the pH balance within cells and for various enzymatic activities. The concentration of hydroxide ions, along with hydrogen ions, determines the acidity or alkalinity of a solution, which is measured on the pH scale. A high concentration of hydroxide ions indicates an alkaline or basic solution, while a low concentration indicates an acidic solution.
