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

Here is the answer for the question – A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M nickel(II) ion solution and another electrode composed of gold in a 1.0 M gold(III) ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25C.. You’ll find the correct answer below

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

The Correct Answer is

Determine the anode and the cathode.Ni2+ + 2e- = Ni(s) E = -0.26 VAu3+ + 3e- = Au(s) E = 1.498 VThe reaction with the higher reduction potential is the cathode, so gold is the cathode. Subtract the standard reduction potential of the half-reaction at the anode from the cathode.1.498 V – (-0.26 V) = 1.76 V

Reason Explained

Determine the anode and the cathode.Ni2+ + 2e- = Ni(s) E = -0.26 VAu3+ + 3e- = Au(s) E = 1.498 VThe reaction with the higher reduction potential is the cathode, so gold is the cathode. Subtract the standard reduction potential of the half-reaction at the anode from the cathode.1.498 V – (-0.26 V) = 1.76 V is correct for A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M nickel(II) ion solution and another electrode composed of gold in a 1.0 M gold(III) ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25C.
