Sort of like saying that a lake is filled with "drinking water."

Finding any of them on another planet or moon would be interesting.
I notice that Wikipedia's entry on salt says "Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts." (it also says "This article is about common table salt. For salts in chemistry, see Salt (chemistry). For table salt used in chemistry, see Sodium chloride. For other uses, see Salt (disambiguation).")
Normally the word "salt" indicates sodium chloride unless it is otherwise clear from context that it might be referring to some other salt.
And there is always the first sentence of the article to clear up what specific chemical you are speaking of.
