How do you remove the excess copper oxide?
Pour it down the sink.
Evaporate it.
Filter it.
Leave it to dry.
The colour of the copper sulfate solution is
(a)
Why do you need to heat the copper sulfate solution over a water bath?
To heat up the acid.
To start to evaporate the salt.
To start to evaporate the water.
To get rid of the salt.
The name for the formation of crystals is
Evaporation
Crystallisation
Condensation
Distillation
Why do you leave the solution in a warm place for a few days?
To stop the water from evaporating.
It looks nice.
To allow the crystals to form slowly.
How would you dry your final crystals?
Use a hair dryer.
Pat them will filter paper.
Add water.
Put them back over a Bunsen burner.
What acid would you need to use if you wanted to make copper chloride crystals?
Sulfuric acid
Phosphoric acid
Hydrochloric acid
Nitric acid
What acid would you need to use to make copper nitrate crystals?
Nitric acid
