can anyone solve it ( half reaction method) oxidation -reduction equation .. can anyone do it...
Show how using half-reactions may be used to balance (relatively) complex oxidation/reduction reactions such as the following reaction in basic solution: Let's try this problem together - feel free to answer the first couple of questions (oxidation states) and then the next person can take over.....by the end we can solve it all together. What is the oxidation state of sulfur (S) in SO32-? What is the oxidation state of sulfur in SO42-? Write the appropriate half-reaction in a basic...

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...
