A student was asked to identify a compound. In an effort to do so, he first dissolved the compound in water. He found that no precipitate formed when hydrochloric acid was added, but when H2S was bubbled into this acidic solution, a precipitate formed. Which one of the following could be the precipitate? NiS AgCl HgS BaS
Is an insoluble ionic compound, such as AgCl,a strong electrolyte or a weak electrolyte?
