WebJul 25, 2013 · H2S is not a strong acid. Lets assume there are HCL (aq) and H2S (aq). Ok, so HCL (aq) will mostly disassociate to H+ and CL- .There are 2 ions here for HCL (aq) (higher boiling point elevation) . For H2S, there is only 1 (H2S does not disassociate) (lower boiling point elevation). Thats what I would think under testing conditions. heath macbethWebBoiling Point Of H2Se.
