Chloride ions

Chloride ions are negatively charged particles formed when chlorine, a common chemical element, gains an electron. They play a vital role in various biological processes, including maintaining fluid balance in cells and transmitting nerve signals. Chloride ions are commonly found in table salt (sodium chloride) and seawater. In the human body, they help regulate acidity and are essential for proper digestive function. Understanding chloride ions is important not only in biology but also in chemistry, as they are key components in many chemical reactions and compounds.
