Balance N2H4 + ClO3- = NO + Cl- || ION ELECTRON METHOD || Half reaction method

This video explains redox balancing in basic solution for the reaction N2H4 + ClO3- = NO + Cl- by ion electron method. Reaction of Hydrazine with Chlorate ion in basic solution is a redox reaction To balance redox reaction, we need to follow certain steps. Step 1 Assign Oxidation number Assign oxidation number for N & Cl. This helps to split the equation into oxidation half reaction & Reduction half reaction. Step 2 Oxidation Half reaction split the equation into OH and RH , then write unbalanced equation in Oxidation Half reaction Step 3 Reduction Half reaction write unbalanced equation in Reduction Half reaction Step 4 Balance the atoms other than H & O in each half reaction individually. Here in Oxidation half reaction Nitrogen atom need to be balanced. While balancing atoms, Take care of electrons too. Step 5 Balance electrons To make the number of electrons equal on both half reaction, Multiply one or both reactions by appropriate number. Now rewrite the reaction by adding two reactions into single after cancelling out equal electrons. Step 6 Balance oxygen atoms Add H2O to balance oxygen atoms Step 7 Balance H-atoms Since reaction is carried out in basic medium add H+ and OH- ions or H2O to balance Hydrogen atoms. Also add same number of OH- ions on other side. But in this reaction hydrogen is automatically balanced, So we can skip this step. Step 8 Charge checking Finally check the charges on both sides. Since both LHS & RHS contains same number of equal charges, The completely balanced net ionic equation is 3 N2H4(l) + 4ClO3-(aq) = 6NO(g) +4Cl-(aq) + 6H2O
