Neutral medium
How are electrons used in acid and basic medium?
Electrochemistry
The same procedure as used on acid medium is applied, for example on balancing using electron ion method to complete combustion of propane. "Unbalanced reaction": C3H8 + O2 → CO2 + H2O "Reduction": 4 H+ + O2 + 4 e– → 2 H2O "Oxidation": 6 H2O + C3H8 → 3 CO2 + 20 e– + 20 H+ As in acid and basic medium, electrons which were used to compensate oxidation changes are multiplied to opposite half reactions, thus solving the equation. 20 H+ + 5 O2 + 20 e– → 10 H2O 6 H2O + C3H8 → 3 CO2 + 20 e– + 20 H+ Equation balanced: C3H8 + 5 O2 → 3 CO2 + 4 H2O
