Alright SPÏDY — let's do this. Here are the solutions for the questions: 20. a) Calculate the oxidation number of sulphur in H₂S₂O₈. [1] Step 1: Assign known oxidation numbers. In H_2S_2O_8, hydrogen has an oxidation number of +1, and oxygen usually has -2. However, H_2S_2O_8 (peroxydisulfuric acid) contains a peroxide linkage (-O-O-), where two oxygen atoms have an oxidation number of -1. The remaining six oxygen atoms have an oxidation number of $-2
