Hyposulfite may refer to:

  • The sulfoxylate anion (SO2−2)
  • The thiosulfate anion (S2O2−3)
  • S2O2−2, a reported sulfur oxyanion. However salts containing S2O2−2 and HS2O2 are not well characterized; they would be conjugate bases derived from the parent thiosulfurous acid (H2S2O2), which is also of doubtful existence.[1]
  • Dithionite (S2O2−4) as in sodium dithionite.[2]
