1. Chemistry Revision: Reactivity Series
Metals and Acid Reactions
Year 8
Week 11

2. Metal and Acid Reactions
WALT: discover the reactivity series of metals by reacting them with acids
I must be able to state the equation for reacting a metal and an acid
I should be able to carry out a practical to discover the reactivity series
I might be able to write out the full word equations for these reactions

3. Last lesson we learnt the gas tests for….
Oxygen…………..
Carbon dioxide ………….
Hydrogen…………..

4. Can you remember how to form a salt?
Acid + alkali >>>>> salt + water

5. A salt is …..
Something formed from an acid…… Table salt (sodium chloride) is just one example

6. You are going to make some salts1. 2.
Acid
Metal

7. Metals we will use are:
Magnesium
Zinc
Iron
Aluminium
Copper
Lead

8. Check your answers with page 232 of the books
Metal
Reaction with acid (how vigorous, fast etc)
Gas produced
Magnesium
Zinc
Iron
Lead
Aluminium
Copper
The more reactive metals will react more vigorously. Use your results to put the metals in order of reactivity.
Check your answers with page 232 of the books
Write a method, results and conclusion
See if you can write out the full word equations for the reactions that have taken place

9. acid + metal >>> salt + hydrogen
e.g.
magnesium + hydrochloric >>> magnesium + hydrogen
acid chloride

10. Plenary What did the results tell you about the reactivity series
How could we have made the results more reliable?
2. Tried with different acids
