What is the chemical symbol for the hydroxyl ion?

The hydroxyl ion is represented by the chemical symbol OH-. This ion consists of one oxygen atom covalently bonded to one hydrogen atom, carrying a negative charge. This negative charge indicates that the hydroxyl ion is a base that can accept protons (H+) or donate electrons during chemical reactions.

Hydroxyl ions play a significant role in various chemical processes, especially in acid-base chemistry and the formation of water. They are commonly found in aqueous solutions, contributing to the properties of bases, as they increase the concentration of hydroxide ions in solution.

Understanding the structure and properties of the hydroxyl ion is crucial in disciplines like chemistry and biology, where reactions involving acids and bases are frequently encountered.
