The 26 pages that link to Hydrogen chloride, each with the reason it gives.

• Dipole momentBroader topic: Its single polar bond makes its molecular dipole a direct example of bond charge separation.

• Volcanic gasBroader topic: It is a volcanic halogen gas that can acidify rain and affect local ecosystems.

• Hydrochloric acidRelated: It is the molecular substance whose dissolution produces this acid.

• Hydrogen fluorideCompared with: Unlike hydrogen chloride, HF is a weak acid in water but penetrates tissue deeply.

• HydroniumCompared with: HCl is a proton source in water, not the ion that carries aqueous positive charge.

• Ammonium chlorideRelated: It can combine with ammonia to produce ammonium chloride.

• Diatomic moleculeBroader topic: HCl illustrates a polar heteronuclear diatomic molecule.

• Phosphorus trichlorideRelated: Hydrolysis of PCl₃ releases hydrogen chloride fumes.

• Hydrogen halideBroader topic: It is manufactured at scale and dissolves in water as hydrochloric acid.

• ChloromethaneRelated: Hydrogen chloride provides the chlorine in the principal industrial synthesis of chloromethane.

• Hydrogen bromideCompared with: HCl is the familiar neighboring hydrogen halide and a useful comparison for HBr.

• Thionyl chlorideRelated: It is released alongside sulfur dioxide when thionyl chloride converts many substrates.

• Acetyl chlorideRelated: Reaction with moisture releases this irritating, corrosive gas.

• Hydrogen iodideCompared with: HCl is a familiar neighboring hydrogen halide with a stronger H–X bond.

• Iron(II) chlorideRelated: Hydrogen chloride can react with iron to produce iron(II) chloride and hydrogen.

• 1,2-DichloroethaneRelated: It is released alongside vinyl chloride during 1,2-dichloroethane cracking.

• Rotational–vibrational spectroscopyBroader topic: Its infrared-active vibration produces a clear rotationally resolved band.

• Titanium tetrachlorideRelated: Hydrolysis of TiCl₄ releases this corrosive gas, creating a major exposure hazard.

• Argon fluorohydrideCompared with: HCl is stable without a cryogenic argon matrix, unlike HArF.

• Benzoyl chlorideRelated: Substitution and hydrolysis reactions release HCl, often requiring a base to capture it.

• Phosphoryl chlorideRelated: Hydrolysis of POCl₃ releases hydrogen chloride, contributing to its fuming behavior.

• Silicon tetrachlorideRelated: It is released when SiCl₄ reacts with water or hydrogen.

• Basic lead phosphiteRelated: Heating PVC can release hydrogen chloride, which accelerates further degradation.

• Cadmium chlorideRelated: Hydrogen chloride may be released in reactions or thermal processes involving chloride salts.

• Chlorosulfuric acidRelated: Hydrolysis of chlorosulfuric acid produces hydrogen chloride alongside sulfuric acid.

• Sulfur dichlorideRelated: Hydrogen chloride can arise when sulfur dichloride reacts with moisture.
