Why is HCl called hydrochloric acid, not just "chloric" acid? I mean, we don't say hydronitric acid, nor do we say hydrosulfuric acid. But then why is HCl called hydrochloric acid, not just chloric acid? (i mean, we do add the hydrogen for acid) My guess is that this is so because the anion (Cl-) of HCl is just a single element, not something like NO3, or SO4...well, u see... But is this why we say hydrochloric, not just chloric? Well, if not, then why?
