I have been staring at the following problem, and I can't seem to get the correct answer. I tried using half reactions and the oxidation number method, but I don't know which works best. Write balance net ionic equations for reaction in acidic solution. ClO3- (aq) + As2S3 (s) --> Cl- (aq) + H2AsO4- (aq) + HSO4- (aq) For the half reaction method, which 2 reactions do I divide this into? I tried this way, ClO3- --> Cl- As2S3 --> H2AsO4- + HSO4- but I suppose this is wrong. Any help, especially with the half reaction method, is welcome and needed.
