WebHydrogen sulfide is the foul-smelling gas that gives rotten eggs their unpleasant odor. It is an excellent source of the S 2-ion, however, and is therefore commonly used in introductory chemistry laboratories. H 2 S is … WebJan 17, 2016 · H2S is a weak acid. H2S is a Brønsted acid, because it is donating a proton to the water. It is also a Lewis acid, because it is accepting a pair of electrons to form the O-H bond in hydronium ion. H2S has two lone pairs on the S, so it can also act as a Lewis base. In the presence of a strong acid like H2SO4, the H2S becomes protonated.
