Balancing a Redox Reaction.. urgent I have an assingment that is due tomorrow for my college chemistry class and i am stuck on the last problem. I need to balance the following redox reaction, but everytime i try it doesnt balance... H2O +I2 + OCl- ? IO3- + Cl- + H3O when i split it up into the half reactions i get I2 + 6H20 ? 2IO3- + 10e- + 12H+ OCl- + 2e- + 2H+ ? Cl- + H2O which adds up to be this 5OCl- + I2 + 2H+ + $H2O ? 2Cl- + 2IO3 + 12H+ i dont get why it doesnt work. can someone show me what to do?? i have already searched the internet for tutorials, and i think i am doing everything correct.
