​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...

Multiple Choice

What can you predict by using an activity series?

• whether a single replacement reaction can occur

• whether a chemical reaction will absorb energy

• the state of a product

• the melting points of elements

Multiple Choice

In the activity series, the more active elements are found

• at the bottom

• in the middle.

• at the top.

• Both (a) and (c)

​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 →

Multiple Choice

Multiple Choice

Will this reaction happen if solid copper is dipped into a solution of zinc nitrate?

• Yes

• No

Multiple Choice

What will be the result of the following:

LiBr + Na ->

• Li will replace Na

• Na will replace Br

• Na will replace Li

• no reaction will occur

Multiple Choice

What will be the result of : Zn + AuCl₂->

• ZnCl₂ +Au

• ZnAu + Cl₂

• no reaction

• ClAu + Zn

Multiple Choice

What would result for the following reaction:

magnesium + silver nitrate -->

• no reaction

• nitrate + silver magnesium

Multiple Choice

If metal A is placed in an ionic solution containing metal B ions and no

reaction occurs, then metal B is most likely

• a halogen

• higher on the activity series.

• not on the activity series.

• a catalyst.

Multiple Choice

According to the activity series,

which of the following single replaceement reactions can occur?

• 2Ni_(s) + MgSO_4(aq) →

• 2Al_(s) + 3KOH_(aq) →

• 3Ca_(s) + Al₂(SO₃)_3(aq) →

• Fe_(s) + 2NaOH_(aq) →
