Question

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).

Answer 1

B Divide the chemical equation into two half-reaction equations, identifying which half-reaction is oxidation and which is reduction

Answer 2

The answer would be A). H2O and OH- are added as needed to the half-reaction equations to make the number of oxygen and hydrogen atoms balance.
