Nickel and aluminum electrodes are utilized to build a galvanic cell. The standard reduction possible for the nickel(II) ion is -0.26 V as well as that of the aluminum(III) ion is -1.66 V.
a. Explain what are the theoretical cell potential assuming standard conditions?
b. Explain which metal is the cathode?
c. Define which statement is true?
Electrons flow from Ni to Al.
Electrons flow from Al to Ni.
The nickel electrode loses mass.
The aluminum electrode gains mass.
d. Write the shorthand notation for this cell. Do not comprise concentrations.
For instance, in shorthand notation your respond might look like Cu| Cu^+||Pd (2+) |Pd
