We’re being asked to determine the standard cell potential (E°cellof the reaction occurring in an electrochemical cell. To calculate for the standard cell potential, use the following equation:

EOcell = EO cathode - EOanode


When a balanced reaction is given, identify the anode and the cathode half-reactions by determining the changes in oxidation states of each species based on the given reaction:

Problem Details

A voltaic cell is constructed from
an Ni2 +  (aq) - Ni(s) half-cell and
an Ag+ (aq) - Ag(s) half-cell.

The initial concentration of Ni2 +  (aq) in the Ni2 +   - Ni half-cell is [Ni2 +  ] = 1.50×10−2 M . The initial cell voltage is +1.13 V .

By using data in Table 20.1 in the textbook, calculate the standard emf of this voltaic cell.
