Question

A cell was prepared by creating the following cells:

  • Anode: a Zr wire in a 1 M Zr4+ solution (Zr4+ + 4e– → Zr (s), E° = –1.45 V)
  • Cathode: a Cu wire in a 1 M Cu2+ solution (Cu2+ + 2e– → Cu (s), E° = +0.337 V)

What is the voltage of this cell?

   

-1.787 V
   

1.113 V
   

-1.113 V
   

1.787 V

 

What is the mass balance for K2SO4?

   

[K+] = 2*([SO42–] + [HSO4–] + [H2SO4])
   

[K+] = 2*[SO42–]
   

[K+] = 2*([SO42–] + [H2SO4–])
   

[K+] = [SO42–]
