What is a Bronsted Acid? Explanation: In an acid base rxn, the proton donor is the acid while the proton receptor is the base. In this case, when hydrogen sulfide, #"H"_2"S"#, donates a proton, the compound left behind will be the bisulfide anion, #"HS"^(-)#, its conjugate base. The trans form predominates at room temperature, and IR measurements indicate it is more stable by around 2.3 kJ/mol. 16 - .
