How to balance redox reactions using the half reaction method


Asked by admin @ in Chemistry viewed by 318 People


Which of the following is not a step in balancing redox reactions in acidic solution, using the half-reaction method?

A) H2O and OH- are added as needed to the half-reaction equations to make the number of oxygen and hydrogen atoms balance.
B) Divide the chemical equation into two half-reaction equations, identifying which half-reaction is oxidation and which is reduction.
C) H2O and H+ are added as needed to the half-reaction equations to make the number of oxygen and hydrogen atoms balance.
D) Multiply each term in one of the half-reaction equations by a factor that will make the number of electrons lost (in the oxidation) equal to the number of electrons gained (in the reduction).
