identification - Which white powders form acids when mixed with water?


I have a mystery acid which isn't citric, boric, or oxalic acid. When mixed with water, it smells pungent, like hydrochloric acid--though I haven't compared them side by side.



Which other white powders form a strong acid upon being combined with water? Is there any powder that decomposes into HCl when mixed with water?


(Note: the mystery acid was sold as part of a set, along with sodium chlorite, for generating chlorine dioxide for use in aquariums.)
