Not to be confused with hydrosulfite, which is another name for the dithionite anion (S 2O2− 4).
Hyposulfite may refer to:
The sulfoxylate anion (SO2− 2)
The thiosulfate anion (S 2O2− 3)
Sodium thiosulfate, a salt containing the thiosulfate anion
S 2O2− 2, a reported sulfur oxyanion. However salts containing S 2O2− 2 and HS 2O− 2 are not well characterized; they would be conjugate bases derived from the parent thiosulfurous acid (H 2S 2O 2), which is also of doubtful existence.[1]
Dithionite (S 2O2− 4) as in sodium dithionite.[2]
