Question

For the following cell, standard potential of copper electrode is 0.337 V and standard cell potential is 0.463 V.

\[\ce{Cu | Cu^{2+} (1 M) || Ag^+ (1 M)  Ag}\]

What is the standard potential of silver electrode?

Options

• −0.463 V

• −0.126 V

• 0.126 V

• 0.800 V

Answer 1

0.800 V

Explanation:

`"E"_"cell"^0` = 0.463 V, `"E"_"Cu"^0` = 0.337 V

`"E"_"cell"^0 = "E"_"Ag"^0 - "E"_"Cu"^0`

∴ `"E"_"Ag"^0 = "E"_"cell"^0 + "E"_"Cu"^0`

= 0.463 + 0.337

= 0.800 V
