Each half reaction in ion electron method is balanced by adding?
Correct answer: C. Electrons on Either the left or right-hand side.
- A. Electrons on the left-hand side only.
- B. Electrons on the right-hand side only.
- C. Electrons on Either the left or right-hand side.
- D. None of these.
Explanation
In the ion-electron method, each half-reaction is balanced by ensuring that the number of electrons is the same on both sides of the equation. This is achieved by adding electrons to one side of the half-reaction, either the left or the right, depending on the specific needs of the reaction. This ensures that the overall charge is balanced. The correct answer is that electrons can be added to either the left or right-hand side of the equation, which makes Option C correct. Options A and B are incorrect because they limit the addition of electrons to one side only. Option D is incorrect as electrons are indeed necessary to balance half-reactions.

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.
