HCl is a covalent compound.
I do not understand why HCl cannot exist as an ionic compound with the combination of hydrogen ions and chloride ions. Is it a matter of electronegativity?
I have once wondered if it is possible to obtain HCl crystals from hydrochloric acid, since I was told that HCl(g) ionizes in water to produce hydrogen and chloride ions. However, I have overlooked the fact that the so-called hydrogen ions exist as hydronium ions instead of pure hydrogen ions.
Does anyone have some thoughts on the reason why HCl should be covalent, and whether it is possible to prepare HCl salt?
