Answer»  There are following steps used-to balance a reaction taking place in basic medium by ion electron method : Step I: Write the skeletal equation and indicate the oxidation number of all the elements. Step II: Find out the species which are oxidised and which are reduced. Step III: Split the equation in two half reactions i.e. oxidation half reaction and reduction half reaction Step IV: Balance the two half reactions separately by using following steps : (i) First of all, balance the atoms of the elements which have undergone a change in oxidation number (ii) Add electrons to whatever side in necessary to make up the difference in oxidation number in each half reaction. (iii) Balance change by adding OH–. (iv) Balance oxygen atoms by adding required number of H2O molecules to the side deficient in O-atoms. (v) H-atoms are balanced by adding H2O molecules equal in number to the deficiency of H atoms and equal number of OH– ions are included in opposite side of the equation. Step V: The two half reactions are multiplied by suitable integers to balance the number of electrons. The half reaction, are then added up.  |
