A galvanic (voltaic) cell consists of an electrode composed of aluminum in a 1.0 M aluminum ion solution and another electrode composed of fold in a 1.0 M gold (III) ion solution connected by a salt bridge. Calculate the standard potential for this cell at 25 degrees celcius.

Note the correct spelling of celsius.
Al(s) + Au^3+ ==> Al^3+ + Au(s)
Look up reduction potential for Al and reverse the sign. Add to the reduction potential of Au to AuIII.
Total is Eo standard cell.
