How would you balance this reaction(it's a half reaction problem): H2O2+ClO2-->ClO2+O2 (basic solution) thanks. i'm just confused b/c its a basic solution. all i know is that you have to add OH to it or something. thanks again for helping. add OH and you will get H2O as a ...

Hello everybody, I'm told that potassium permanganate is dissolved in an aqueous buffer of ammonia and ammonium at equal concentrations (1M), and treated with 1M sodium hypochlorite, the permanganate ion is reduced to insoluble manganese dioxide as the hypochlorite ion is ...

How do I balance the following equation by the half-reaction method (it takes place in basic solution)? Fe(OH)2(s) + O2(g) = Fe(OH)3(s) the answer is 4Fe(OH)2(s) + 2H20(l) + O2(g) = 4Fe(OH)3(s) but how do I work it out?
