H 2S react with SO 3 or HSO 3Cl, forming thiosulfuric acid H 2S 2O 3, as the analogous reaction with H 2S 2 forms disulfonomonosulfonic acid HS 2SO 3H; similarly polysulfanes H2Sn (n = 2–6) give HSnSO3H. Reactions from both ends of the polysulfane chain lead to the formation of polysulfonodisulfonic acid HO3SSnSO3H. Many methods exist for the synthesis of these acids, but the mechanism is unclear because of t… WebThe general formula of polythionate ion is S n + 2 O 6 2 − .
