Displacement reactions
Task A: Displacement reactions
1) Some blue copper sulfate solution was poured into a test tube.
An iron nail was added. An orange/brown solid gradually appeared.
Some students try to explain the test. Who do you agree with
and why?
copper
sulfate
solution
iron nail
The reaction has made copper.
Copper is insoluble.
Laura
It is copper that has come out of the nail.
Alex
The iron nail made the copper in the copper sulfate
become insoluble.
I think the copper sulfate has changed the colour of
the iron.

2) A coil of copper wire was placed into a solution of silver nitrate.
a) Tick,
a
b
c
the statement that best explains the appearance of solid silver.
Silver dissolved out of the copper when it was placed in the solution.
Adding the copper wire made the silver in the solution insoluble.
The product of the reaction between copper and silver nitrate is silver,
which is insoluble.
b) Complete the word equation for the reaction:
copper + silver nitrate → __________ + __________
c) Predict what would happen if the copper wire was placed in a solution of sodium
nitrate. Give a reason for your prediction.

Task B: Displacement reactions practical
1) Some students are carrying out a displacement reaction practical to find out
the order of reactivity of the metals: magnesium, copper and tin.
a) What is a displacement reaction?
b) Draw a circle around the metal salts they should use in the experiment.
copper sulfate,
zinc sulfate,
tin chloride,
magnesium sulfate,
iron nitrate
c) Why is it better to carry out the experiment in a spotting tile rather than
using test tubes?
d) How will the students know if a reaction has occurred?
potassium
sodium
calcium
magnesium
aluminium
carbon
zinc
iron
tin
lead
hydrogen
copper
silver
gold
platinum
2) Use the reactivity series for metals to complete the word
equations for the following displacement reactions.
a) calcium + zinc sulfate → __________ + __________
b) iron + silver nitrate→ __________ + __________
c) lead + sodium chloride → __________ + __________
d) aluminium + tin chloride → __________ + __________

Task C: Extracting metals
potassium
sodium
calcium
magnesium
aluminium
carbon
zinc
iron
tin
lead
hydrogen
copper
silver
gold
platinum
You may need to refer to the reactivity series for metals to answer
some of these questions.
1) Name a metal ore.
2) Why is carbon included in the reactivity series?
3) Draw a circle around the metals that can be extracted
from their metal ores using carbon.
sodium,
zinc,
aluminium,
platinum,
calcium,
iron,
copper,
gold
4) Suggest why an alternative method of extraction is used to extract very reactive
metals from their ores.
5) Some carbon was mixed with a copper ore and was heated. At the end of the
reaction, an orange-brown deposit was observed.
a) Name the orange-brown deposit.
b) Write a word equation for the reaction.
