Balance the following redox reactions using the oxidation number method. Show your step-by-step solution for each.
PbO + NH3 → Pb + N2 + H2O
Br - + ClO - + H + → Br2 + Cl - + H2O
HClO3 + H2S → S8 + HCl + H2O
MnSO4 + PbO2 + H2SO4 → HMnO4 + PbSO4 + H2O
Method Method Redox reactions are generally balanced using two processes. The first method is based on the redox reaction’s division into two reactions where one is involved in oxidation and the other in reduction (half reaction method) and the second one is based on the reducing and oxidizing molecule’s oxidation number variation (oxidation number method).
