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 -1.66 V.
a. What is the theoretical cell potential assuming standard conditions?
b. Which metal is the cathode?
c. 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. Type the shorthand notation for this cell. Do not include concentrations.
For example, in shorthand notation your answer might look like Cu|Cu + | |Pd2+|Pd
