Hello, I am trying to balance a tricky (skeleton) reaction using the half reaction method: CrI3 (s) + H2O2 (aq) → CrO42- (aq) + IO4- (aq) I ended up using H2O to balance the peroxide for the reduction half and pulled the rest of the equation down for the oxidation half since Cr and I both lose electrons. The final result was: 27H202 + 2CrI3 -----> 2CrO4^2- +6IO4^- + 22H2O + 10H+ for acidic and... 27H202 + 2CrI3 +10 OH^- -----> 2CrO4^2- +6IO4^- + 32H2O for basic Atoms and charges look balanced but I am feeling a bit uncertain about my method. Can you please confirm whether this is correct? Thank you, Carolyn
