Nickel and aluminum electrodes are utilized to build a galvanic cell. State the standard reduction potential for the nickel (II) ion is -0.26V and that of the aluminum (III) ion is -1.66V. Type the shorthand notation for this cell. Do not include concentrations. For instance, in shorthand notation your answer might look like Cu|Cu^+||Pd^(2+)|Pd. To enter a vertical line, type shift backslash.

This is put into the Mastering Chemistry system and it says it is wrong
Al shift+backslash Al(3+) shift+backslash shift+backslash Ni(2+) shift+backslash Ni
