In Ion electron method, while balancing oxygen and Hydrogen atoms _.
Correct answer: B. First balance Oxygen
- A. First balance Hydrogen
- B. First balance Oxygen
- C. Balance both at the same time
- D. Order doesn't matter
Explanation
Determine the number of oxygen and hydrogen atoms on both sides of the chemical equation. Then, we add water molecules to balance the number of oxygen atoms and hydrogen ions (H+) or hydroxide ions (OH-) to balance the number of hydrogen atoms. The water molecules and ions are added as needed until the equation is balanced. OPTIONS A, C & D are incorrect.

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.
