Chloridionerne

Chloridionerne is the Swedish term for chloride ions. A chloride ion is an anion with the chemical formula Cl⁻. It is formed when a chlorine atom gains one electron to complete its outer electron shell. Chlorine is a halogen, and its atoms readily accept an electron to achieve a stable electron configuration. The resulting ion carries a negative charge.

Chloride ions are ubiquitous in nature and play a crucial role in various biological and chemical processes. In biological systems, chloride ions are essential electrolytes, contributing to fluid balance, nerve impulse transmission, and stomach acid production. The concentration of chloride ions in bodily fluids is tightly regulated.

Chemically, chloride ions are a common component of many ionic compounds, such as sodium chloride (table salt). They can be found dissolved in water, forming aqueous solutions. The presence of chloride ions in water is often an indicator of salinity. In analytical chemistry, the detection and quantification of chloride ions are important for water quality testing and industrial processes. The ionic radius of a chloride ion is larger than that of a neutral chlorine atom due to the added electron repelling the electron cloud.
