bichloride
/'bai'klɔ:raid/
Definition
Noun: A chemical compound containing two atoms of chlorine per molecule. This term is primarily used in specific chemical nomenclature, most notably for mercury(II) chloride (HgCl₂), historically known as "bichloride of mercury."
Usage
The word "bichloride" is a technical term used in chemistry. It is often part of a compound name specifying the metal or cation to which the two chlorine atoms are bonded. Its use in general language is rare.
Examples
- The disinfectant was a solution of bichloride.
- Bichloride of mercury was once used as an antiseptic, though it is highly toxic.
- In the old formula, the compound was listed as a tin bichloride.
Advanced Usage
- The prefix "bi-" in this context is an older chemical naming convention often synonymous with "di-," indicating two atoms. Modern systematic nomenclature typically uses "dichloride" (e.g., mercuric dichloride, stannous dichloride). Therefore, "bichloride" is considered somewhat archaic but may still be encountered in historical texts or specific industrial contexts.
