For the given cell arrangement identify incorrect statement
given `E^@_(Cu^(2+)//Cu)` = 0.34V &` E^@_(Zn^(2+)//Zn) = -0.76V`

A

If `E_("ext") gt 1.1V, Zn` dissolves at Zn electrode and Cu deposits at Cu electrode

B

If `E_("ext") gt 1.1 V, e^(-)` flows from Cu to Zn

C

If `E_("ext") lt 1.1 V, Zn` dissolves at anode and Cu deposits at cathode

D

If `E_("ext")=1.1V`, no flow of `e^(-)` or current occurs

Text Solution

Verified by Experts

The correct Answer is:
A
Zn does not dissolve at Zn electrode when `E_("ext") gt 1.1V`
