According to reactivity series of metals how do we know that there is no reaction between two metals?should the metal be placed below hydrogen in the reactivity series?

Expert Answer
The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.
magnesium metal can also displace zinc ions in solution by the reaction:
Mg(s) + Zn2+ ? Zn(s) + Mg2+
This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen
Mg(s) + Zn2+ ? Zn(s) + Mg2+
This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen
a metal like copper to zinc ions will not displace the zinc since copper appears lower than zinc on the table.
