Pick out the wrong statement, An electrochemical cell stops working only when

A

electrode potential of the two half cells becomes equal

B

whole of the metal used as cathode is consumed

C

whole of the metal used as anode is consumed

D

molar concentrations in the two half cells

Text Solution

Verified by Experts

The correct Answer is:
B,C,D
An electrochemical cell stops working when
`E_("anode")=E_("cathode")`
at this point none of the electrolyte or electrode used is fully consumed.
