Question

A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M 1.0 M nickel(II) ion solution and another electrode composed of silver in a 1.0 M 1.0 M silver ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25 °C . 25 °C.

Answer 1

Answer:

So the standard electrode potential of the cell is 1.05 V

Explanation:

electrode composed of nickel in a 1.0 M

1.0 M nickel(II) ion solution and another electrode composed of silver in a 1.0 M 1.0 M silver ion solution,

connected by a salt bridge. Calculate the standard potential for this cell at 25 °C .

2Ag+ + Ni -----> 2 Ag + Ni +2

Eocell = Eo cathode - Eo anode

= Eo Ag+/Ag - Eo Ni+2/Ni

=0.80 - (-0.25)

=0.80 + 0.25

= 1.05

So the standard electrode potential of the cell is 1.05 V
