If in separate solutions of nitrates of Sn2 +, Zn2 + and Cd2 + we put a coin of Ag (s) in each one it is expected that Ag (s) ...

Zn2 + (ac) + 2e = Zn (s) E ° = -0.76V
Sn2 + (ac) + 2e = Sn (s) E ° = -0.14V
Cd2 + (ac) + 2e = Cd (s) E ° = -0.40V
Ag + (ac) + e = Ag (s) E ° = + 0.80V

A. React only with Zn2 + (ac)
B. React only with Sn2 + (ac)
C. React only with Cd2 + (ac)
D. Silver will react with everyone
E. Silver will not react with any
