Thiosulfate salts are oxidized by strong oxidizing agents such as chlorine, bromine, permanganates, and chromates to form sulfates, among other products. If water is present, sulfuric acid could also be produced. If the oxidizing agent is a halogen (fluorine, chlorine, bromine, iodine), then the corresponding hydrogen halide will be produced as well (Barberá, J. J., Metzger, A. and Wolf, M. 2000. Sulfites, Thiosulfates, and Dithionites. Ullmann's Encyclopedia of Industrial Chemistry (Online)).
Sulfates are weak reducing agents, and react with a variety of oxidizing agents to form different products. Sulfates can reduce iodates to iodides, dichromates to chromium (III), and halogens to hydrogen halides in the presence of water (Barberá, J. J., Metzger, A. and Wolf, M. 2000. Sulfites, Thiosulfates, and Dithionites. Ullmann's Encyclopedia of Industrial Chemistry (Online)).
