Trithionate is an oxyanion of sulfur with the chemical formula. It is the conjugate base of trithionic acid. Dilute sodium hydroxide hydrolyzes tetrasulfur tetranitride as follows, yielding sodium thiosulfate and sodium trithionate:


 * 2 + 6 NaOH + 9  →  + 2  + 8

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