1. 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

2. The Reactivity of Metals Reactivity – a measure of how readily and violently a substance will react with another substance

3. Grrrunt!!! P lease Potassium S top Sodium C alling Calcium M y Magnesium Z ebra Zinc I n Iron C lass, Copper S he Silver G runts! Gold To help us remember…

4. The Reactivity of Metals Displacement – when a more reactive metal takes the place of another one in a compound

5. The Reactivity of Metals Angelina is more reactive than Jennifer…. …so Angelina displaces Jennifer and wins Brad!

6. The Reactivity of Metals What about a real chemical reaction…? …Magnesium and Copper Sulphate Magnesium + Copper Sulphate Copper + Magnesium Sulphate

7. 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!!

8. The Reactivity of Metals True or False? Silver reacts quickly with other substances FALSE

9. The Reactivity of Metals True or False? Copper is very reactive FALSE

10. The Reactivity of Metals True or False? Calcium is close in reactivity to magnesium TRUE

11. Sodium could displace copper from copper sulphate solution TRUE The Reactivity of Metals True or False?

12. Gold could displace silver from silver nitrate solution FALSE The Reactivity of Metals True or False?

13. The Reactivity of Metals zinc + iron sulphate  iron + zinc sulphate copper + sodium chloride  NO REACTION sodium + silver nitrate  silver + sodium nitrate
