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 elect
rode 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.
This is not a redox reaction. None of the species are reduced and none are oxidized
Explanation:
In a redox reaction at least one species must be oxidized and another reduced. You see this by a change in oxidation number. In this question the oxidation numbers are the same before and after the reaction.
This reaction is called the electrolysis of water. The balanced reaction is: 2H2O = 2H2 + O2 We are given the amount of O2 produced from the electrolysis reaction. This will be the starting point of our calculation.
