When there is more than one cations in the aqueous solution of an electrolyte, the ions discharge at the cathode can he predicted from the reactivity order of elements given in the electrochemical series. Which of the following is correct decreasing order of discharge of positive ions at cathode?
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The correct answer is Option A, the correct decreasing order of discharge of positive ions at the cathode based on the reactivity order of elements given in the electrochemical series.

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.
