In a galvanic cell Copper compartment gets a net negative charge due to the arrival of _.
Correct answer: B. Electrons
- A. Free charge from zinc sulfate solution
- B. Electrons
- C. Protons
- D. Zinc ions
Explanation
In a galvanic cell, copper loses electrons to form copper ions, giving the copper compartments a negative charge.

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.
