In acidic solution MnO4- oxidizes H3AsO3, a weak acid, to H3AsO4, a weak acid, and is reduced to Mn2+. Write the balanced net ionic equation for this reaction. How many H+ are there in the balanced equation?

1. In the equation Mn goes from +7 to +2 and As goes from +3 to +5. That should give you the information to balance. Here is a site that may help but please re-post if you have a more detailed question about the procedure.
