Question

Is `HCl` an ionic salt or covalent molecule?

Answer 1

`H-Cl` is a polar covalent molecule to a first approximation........

Explanation:

And of course, we know that `H-Cl` is molecular because it is supplied in the lab as a gas; its boiling point is `−85.05` `""^@C`. Of course this gas has substantial water solubility, and when dissolved in water we get `"hydrochloric acid"`, in which the `H-Cl` bond has been ionized to form `H_3O^+` and `Cl^-`.
