8.18 Balance the following redox reactions by ion – electron method
(a) (In basic medium)
reduction half reaction
(+7 to +4)
Add 3 electron on LHS side and after that to balance charge add OH ions. And to balance O atom add water molecule on whichever side it needed
equalising the no. of electrons by multiplying the oxidation half by 3 and reduction half by 2 and then add it.
