#HCl# is called hydrochloric. How would you write an acid ionization reaction equation for this acid?

#HCl(g)darr + H_2O(l) rarr H_3O^+ + Cl^-#


Any example of acid base behaviour is modified by the properties of the solvent. Generally, we encounter acid/base behaviour in aqueous solution, and the acidium ion is conceived to be #H_3O^+#, likely a cluster of water molecules with an extra #H^+# added.

For strong acids such as hydrochloric acid and sulfuric, the extent of ionization is almost quantitative.
