Question

Why does a galvanic cell become dead after some time ?

Answer 1

Answer 2

Galvanic cells become dead after some time because of discharging.

• A galvanic cell is an electrochemical cell in which chemical change produces electricity.
• In this process, two electrodes are taken anode and a cathode.
• The anode is a negative electrode at which oxidation occurs whereas the cathode is the positive electrode and where reduction occurs.
• During the process, oxidation of Zn to Zn2+ ions causes discharging of zinc metal into the solution.
• When all the Zn2+ is used by there is no more oxidation-reduction reaction and no further flow of electrons. hence, the cell stops working or becomes dead.
