# Metal Activity Series

## Key Questions

• The activity series allows us to predict whether a metal displacement reaction will occur.

We can use the series to predict whether a metal displacement reaction will occur.

For example, zinc is above copper in the series. We predict that placing a strip of zinc metal in a copper(II) sulfate solution will produce metallic copper and zinc sulfate.

Copper is below zinc in the series. We predict that a strip of copper placed into a zinc sulfate solution will not produce a reaction.

The metal reactivity series lists metals in order of their reactivity, from highest to lowest from top to bottom. A metal listed above another metal will replace that metal in a single replacement (single displacement) reaction.

#### Explanation:

Example 1.
Does the following reaction occur?
"Mg(s)"+"CuCl"_2("aq")$\rightarrow$$\text{MgCl"_2("aq")+"Cu(s)}$

"Cu(s)"+"MgCl"_2("aq")$\rightarrow$$\text{CuCl"_2("aq")+"Mg(s)}$?
Therefore, "Cu(s)"+"MgCl"_2("aq")$\rightarrow$$\text{no reaction}$
