3. Flame test

4. Combustion, rusting, oxidation, oxygen

5. Candle burning in bell jar

6. When a substance reacts with oxygen, it gains oxygen and becomes oxidised.
Some oxidation are fast such as combustion. Others are slow, such as rusting.

7. In groups recap everything you know about oxygen:
colourless gas
Has no smell
Slightly soluble in water.

8. A test for oxygen. Oxygen makes a glowing splint relight.

9. How to collect oxygen.

11. Oxygen and oxidation L.O.:
Explain how to use flame tests to identify the presence of a particular metal.
Know how to collect oxygen produced in reactions
Know a simple laboratory test for oxygen
Explain what oxidation is.

12. The reactivity series L.O.: Remember the reactivity series.
Recall a simple test for hydrogen.
Recall the products of the reaction between an acid and a metal.

13. Demo.

14. Reaction of acid with metals

15. increasing reactivity
The reactivity series
The reactivity series is the list of metals placed in order of their reactivity.
One way to remember this order is to learn this silly sentence:
potassium
sodium
calcium
magnesium
aluminium
zinc
iron
lead
copper
silver
gold
Please

increasing reactivity
Platinum

16. What is the order of metals?

17. Metals and acid – general equation
Gold is an unreactive metal that does not react with acid.
Other metals, such as magnesium and zinc, react with acid producing bubbles of gas.
The “squeaky pop” test shows that this gas is hydrogen.
When a metal reacts with acid, the products are a metal salt and hydrogen. What is the general equation for the reaction of a metal with acid?
metal
acid
metal salt
hydrogen
How does the type of acid affect the type of salt produced?
