Each half reaction in ion electron method is balanced by adding:
Correct answer: C. Both left or right hand side
- A. Electrons on left hand side
- B. Electron on ride hand side
- C. Both left or right hand side
- D. None of these
Explanation
Each reaction is balanced by adjusting coefficients and adding H2O, H+, and e− in this order: Balance elements in the equation other than O and H. Balance the oxygen atoms by adding the appropriate number of water (H2O) molecules to the opposite side of the equation.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
