Trithionate is an oxyanion of sulfur with the chemical formula S
3O2−
6. It is the conjugate base of trithionic acid.[1] Dilute sodium hydroxide hydrolyzes S
4N
4 as follows, yielding sodium thiosulfate and sodium trithionate:
- 2 S
4N
4 + 6 NaOH + 9 H
2O → Na
2S
2O
3 + 2 Na
2S
3O
6 + 8 NH

Certain sulfate-reducing bacteria have been known to use the compound in respiration.[2]
