​Replacement

​Activity Series

​Sometimes we combine a metal and an aqueous salt, and... nothing happens.

​We can predict if a reaction will occur by using the Activity Series of elements!

​The solid element WILL replace the aqueous element IF it is HIGHER on the Activity Series.

The solid element CANNOT replace the aqueous element if it is LOWER on the Activity Series.

When there ISN'T a reaction...

​Examples:

Using the Activity Series, determine if a reaction will occur for each pair of reactants. Then, predict the products.

​1. CuSO₄ + Na →

​2. Ag + ZnCl₂ →
