The Reactivity of Metals

Today’s Objectives

By the end of this lesson, you will:

see that a metal will displace a less reactive metal from a solution of one of its salts

remember the reactivity series

be able to work out the products of displacement reactions to write word equations

The Reactivity of Metals

Reactivity – a measure of how readily and violently a substance will react with another substance

Grrrunt!!!Please Potassium

Stop Sodium

Calling Calcium

My Magnesium

Zebra Zinc

In Iron

Class, Copper

She Silver

Grunts! Gold

To help us remember…

The Reactivity of Metals

Displacement – when a more reactive metal takes the place of another one in a compound

The Reactivity of Metals

Angelina is more reactive than Jennifer….

…so Angelina displaces Jennifer and wins Brad!

The Reactivity of MetalsWhat about a real chemical reaction…?

…Magnesium and Copper Sulphate

Magnesium + CopperSulphate

Copper + Magnesium Sulphate

The Reactivity of Metals

- Place four pieces of one of the metals in a spotting tile, each piece in a separate well

- Cover the metal with a few drops of a metal salt solution

- Record results in table

Remember to wear your safety goggles!!
