During electrolysis, the gm of product produced (m) and when plotted against the electric charge Q′ in faradays, which of the following plot is correct?
Correct answer: B. Option B: A straight line with a positive slope passing through the origin
- A. Option A: A horizontal line
- B. Option B: A straight line with a positive slope passing through the origin
- C. Option C: A curve that starts at the origin and curves upwards
- D. Option D: A straight line with a negative slope
Explanation
According to Faraday's laws of electrolysis, the mass of a substance produced at an electrode during electrolysis is directly proportional to the total electric charge passed through the electrolyte. This means the graph of mass (m) versus electric charge (Q') should be a straight line with a positive slope passing through the origin. This is because if no charge is passed, no mass is produced, confirming the graph should start from the origin. Option B correctly represents this relationship. Options A, C, and D depict incorrect relationships: Option A suggests no change in mass with increasing charge, Option C suggests a non-linear relationship, and Option D implies an inverse relationship, all of which contradict Faraday's laws.

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.
