Question

why the elecrto chemical cell stop to perform his function​

Answer 1

Answer:

When one compound of in the anode of an electrochemical cell is oxidized, those electrons serve to reduce the compound at the cathode side. When the material at anode no longer has electrons to lose, the reaction stops and cell stops working.

Explanation:

Electrochemical cells stop working after some time because, When one compound of in the anode of the electrochemical cell is oxidised, those electrons serve to reduce the compound on the cathode side.

Answer 2

Answer:

When one compound of in the anode of an electrochemical cell is oxidized, those electrons serve to reduce the compound at the cathode side. When the material at anode no longer has electrons to lose, the reaction stops and cell stops working.
