In Electrochemical Cells Reduction takes place at?
Correct answer: B. Cathode
- A. Anode
- B. Cathode
- C. At the surface of electrolyte
- D. None of these
Explanation
In an electrochemical cell, the cathode (+) is the one that gains electrons hence the element that is being reduced gains electrons. Eg; cu2+ + 2e = cu STANDARD C3ELL (E)= +0.34v 2H+ +2e= H2 E=0.00V cu2+ is being reduced because it is more positive hence moves forward and hence is gains electrons, hence it will be on the cathode because it gains electrons

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.
