In chemistry,<unk> s are salts resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (mostly amines). This is also known as muriate, derived from hydrochloric acid's other name: muriatic acid.
For example, reaction of pyridine (C5H5N) with hydrochloric acid <unk>  yields pyridine<unk>  (C5H5N·HCl). Even though this style of formulas is often used for denoting the<unk> s, the dot incorrectly implies that the two molecules are weakly bonded together. It is the salt C5H5NH+ Cl- with correct chemical name pyridinium chloride.
