If you want to prepare a galvanic cell with the redox couples the Sr²⁺/Sr (E⁰= - 2.89V) and Zn²⁺/Zn (E⁰= - 0.76V), which couple will be in the cathode and which couple will be in the anode?

b) Write a complete galvanic cell with these two redox couples (use the conventional notation of cells to denote the phase boundaries). The electrolytic solutions used are Zinc sulfate and Strontium sulfate.

c) How much will be the standard potential of the cell?
