|
A more reactive metal can displace a less reactive metal from a compound. |
|
What happens during a displacement reaction? investigate the displacement reactions of metals and metal ion solutions to determine the reactivity series of metals |
|
|
|
Students should be able to deduce an order of reactivity of metals based on experimental
results. |
|
What would the independent, dependent and control variables be for a quantitative investigation into the reactivity of metals? Students deduce |
|
|
|
The non-metals hydrogen and carbon are often included in the reactivity series. |
|
Where in the reactivity series does carbon appear and which elements can be displaced by carbon? Show the reactivity series and ask students to compare their results against the known series. Students to suggest why they might have different results. Discuss if their experiments are reproducible. |
|
|
|
The reactions of metals with water and acids are limited to room temperature and do not include reactions with steam. |
|
What conditions are standard when investigating the reactivity of metals with water and acids? Teacher to question students about CVs during the demo to lead to these points |
|
|
|
Metals can be arranged in order of their reactivity in a reactivity series. |
|
What is the list of metals (and non-metals) in the reactivity series, from most reactive to least reactive? Show this mnemonic and then ask students if they can improve it to make it more memorable for them: https://www.youtube.com/watch?v=XWjQUgq2u9E |

|
Students should be able to recall and describe the reactions, if any, of potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper with water or
dilute acids and where appropriate, to place these metals in order
of reactivity |
|
How do each of the following metals react with each of water and dilute acids: potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper? Write a conclusion for their experiment that includes references to observations made for each metal with acid and acids.
GF: Discuss why sacrificial metals are used in the production of boats and bridges |

|
Student should be able to write ionic equations for displacement reactions |
|
Write the ionic equation for the displacement reaction between copper ions and magnesium Write ionic equations for each result from their experiment |
