Explanation:
The unbalanced redox equation is as follows:
Cu+NO3−→Cu2++NO2
All atoms other than H and O are balanced.
The oxidation number of Cu changes from 0 to 2. The change in the oxidation number of Cu is 2.
The oxidation number of N changes from 5 to 4. The change in the oxidation number of N is 1.
The increase in the oxidation number is balanced with decrease in the oxidation number by multiplying NO3− and NO2 with 2..
Cu+2NO3−→Cu2++2NO2
O atoms are balanced by adding 2 water molecule on RHS.
Cu+2NO3−→Cu2++2NO2+2H2O
To balance H atoms, add 4 H+ on LHS.
Cu+2NO3−+4H+→Cu2++2NO2+2H2O
