A galvanic cell consists of a Al³⁺/Al half-cell and a standard hydrogen electrode.If the Al³⁺/Al half-cell standard cell functions as the anode,and the standard cell potential is 1.66 V,what is the standard reduction potential for the Al³⁺/Al half-cell?

Question

Quizplus · Accepted Answer

The standard hydrogen electrode has a potential of 0 V. Since the Al³⁺/Al half-cell functions as the anode, it is oxidized, and its potential is negative. The cell potential is 1.66 V, so the reduction potential for Al³⁺/Al is -1.66 V.
