What is cl4-?

Cl4- is the chemical formula for tetrachloride ion. It is made up of a central chlorine atom covalently bonded to four other chlorine atoms. The molecule is overall negative due to the presence of an additional electron, making it an anion. Tetrachloride ion is considered a stable molecule and is commonly used in industry as a solvent, specifically for dry cleaning. It can also be used as a precursor for the production of other chlorine compounds. However, it is also highly toxic and potentially carcinogenic, so caution must be taken when handling and working with it.
