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. WebHF is a weak acid neutralized by NaOH. HF has a higher boiling point than HCl. CH4 molecules interact more closely in the liquid than in the gas phase. Ice, H2O, has a solid structure with alternating H?O interactions. H2Te has a higher boiling point than H2S.
