Describe an electrochemical cell tthat would have the follow

Describe an electrochemical cell tthat would have the following net equation, by answering the following questions. Fe(s)+Ni^2(aq)-->Ni(s)+Fe^2+(aq)

1. Write the reduction and oxidation half-equations for the cell.

2. Calculate the expected net volata for this cell.

Solution

Ox reaction: Fe ---> Fe(2+) + 2e
Red reaction: Ni(2+) + 2e ---> Ni

Given that Fe/Fe(2+) is +0.44V and Ni(2+)/Ni is -0.26V, the net voltage is +0.18V
