Question

Nickel–Aluminum Galvanic Cell Nickel and aluminum electrodes are used to build a galvanic cell. The standard reduction potential for the nickel(II) ion is 0.26 V and that of the aluminum(III) ion is 1.66V Part A What is the theoretical cell potential assuming standard conditions? Express your answer in volts. Part D Type the shorthand notation for this cell. Do not include concentrations. For example, in shorthand notation your answer might look like Cu|Cu^+||Pd^(2+)|Pd. To enter a vertical line, type shift+backslash.

please help

Explanation / Answer

Part A: Calculation of standard cell potential

Eocell = Eoredn(cathode) - Eoredn(anode)

Nickel electrode will become cathode, because it has higher reduction potential and therefore Al become anode.

Eocell = -0.26 - (-1.66) = 1.4 V

Part B

Cell representation: Al | Al3+ || Ni2+ | Ni

Anode is shown on left hand side and cathode is shown on right hand side. Two electrodes are separated by salt bridge (||)
