Which reaction below will occur when Cd (s) and Zn (s) are added to a solution that contains both Cd2+ and Zn2+ ions?
Cd (s) + Zn2+ (aq) → Cd2+ (aq) + Zn (s)
Zn (s) + Cd2+ (aq) → Zn2+ (aq) + Cd (s)
Both of the above reactions occur.
Neither of the above reactions occur.
Cd (s) + Zn2+ (aq) → Cd2+ (aq) + Zn (s)
Zn (s) + Cd2+ (aq) → Zn2+ (aq) + Cd (s)
Both of the above reactions occur.
Neither of the above reactions occur.

Here is a link to the activity series. A METAL will displace another metal ION below it in the activity series.
Therefore, Zn will displace Cd^2+ but not the other way around.

Zn(s) + Cd*2+(aq) ==> Cd(s) + Zn^2+(aq)
Therefore, Zn will displace Cd^2+ but not the other way around.

Zn(s) + Cd*2+(aq) ==> Cd(s) + Zn^2+(aq)
