WebOxymercuration-demercuration is the reaction when alkene treated with mercuric salt [Hg(OAc) 2] and alcohol [ROH], and ether is formed. Oxymercuration (ROH) Explained: … Mercury(II) acetate can be produced by reaction of mercuric oxide with acetic acid. Mercury(II) acetate in acetic acid solution reacts with H2S to rapidly precipitate the black (β) polymorph of HgS. With gentle heating of the slurry, the black solid converts to the red form. The mineral cinnabar is red HgS. The precipitation of HgS as well as a few other sulfides, using hydrogen sulfide is a step in qualitative inorganic analysis.
