Trithionate
WebA Kinetic Study of Rearrangement and Degradation Reactions of Tetrathionate and Trithionate in Near-Neutral Solutions. Inorganic Chemistry 2010 , 49 (22) , 10273-10282. Many members of the polythionates have been characterized: dithionate, trithionate, tetrathionate, pentathionate, etc. These salts are often generated by oxidation of thiosulfate. For example, tetrathionate is obtained by oxidation of thiosulfate ion with iodine (reaction is used in iodometry): S2O2−3 + I2 → S4O2−6 + 2 I
