    Redox equation is in which oxidation and reduction occur simultaneously. Balancing of such equation in basic medium have two extra steps as compare to acidic medium.steps are given below:  1. Assigning the oxidation numbers to each element in whole given chemical equation.  2. Figure out those elements in which oxidation and reduction is occurring.  3. Split the equation in two halves i.e oxidation half reaction and reduction half reaction.  4. Balance the number of atoms first then balance the charges by balancing electrons.hydrogen and oxygen are balanced by H+ and H2O respectively.  5. Add two half reactions and deduct same items like electrons which are present on both side of equation.  6. Now add one OH- for each H+ on both side of sum equation.  7. Now deduct waters present both side of equation. check the equation is balanced or not by counting atoms and charges.   Practice chemical equation: Zn + NO 3 -1  ...
