Write the formula of acetic acid as C2H4O2. In assigning oxidation numbers in this compound, H is +1, O is -2. So, each carbon will have an average oxidation number of:
2(C) + 4(+1) + 2(-2) = 0
Solving this gives and average oxidation number for carbon of 0
In CO2, carbon has a +4 oxidation number. So, to balance the reaction:
C2H4O2 + 2 H2O --> 2 CO2 + 8 H+ + 8 e-
2(C) + 4(+1) + 2(-2) = 0
Solving this gives and average oxidation number for carbon of 0
In CO2, carbon has a +4 oxidation number. So, to balance the reaction:
C2H4O2 + 2 H2O --> 2 CO2 + 8 H+ + 8 e-
