Reduction Half-Reactions with Corresponding Standard Half-Cell Potentials Are Shown Below

Short Answer

Reduction half-reactions with corresponding standard half-cell potentials are shown below.
Zn²⁺(aq)+ 2 e^- → Zn(s)E° = - 0.76 V
Al³⁺(aq)+ 3 e^- → Al(s)E° = - 1.66 V
The standard potential for the galvanic cell that uses these two half-reactions is ________ V.
