This video tutorial explains how to find the oxidation number for sulfur in the thiosulfate ion (S2O3 2-). It begins by calculating the average oxidation number for sulfur, using an equation to balance the charges. The video then discusses the structural differences in the thiosulfate ion, highlighting that the sulfurs have different chemical contexts. The tutorial concludes with a note on the importance of understanding these differences and provides links for further exploration.
