What is the basic principle of balancing the equation by Oxidation number?

Correct answer: C. Electrons lost are equal to electrons gained

  • A. Electrons lost are less than electrons gained
  • B. Electrons lost are more than electrons gained
  • C. Electrons lost are equal to electrons gained
  • D. None of these

Explanation

The basic principle used when balancing the equation by oxidation number is that electrons lost are equal to electrons gained. Thus while balancing a reaction the increase in oxidation number of one atom must be made equal to the decrease in oxidation number of the other.

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.
