Extracting copper by electrolysis

Question 1

What are metal ores?

Answer 1

metal ores are the compound that form when metals in the ground react.

Question 2

what is coppers ore called?

Answer 2

malachite

Question 3

how do you make copper oxide from malachite?

Answer 3

heat it up to form copper oxide

this is called thermal decomposition

Question 4

what is made when copper oxide is reacted with sulfuric acid?

Answer 4

copper sulfate

Question 5

what is the method for extracting copper using electrolysis?

Answer 5

measure a set amount of sulphuric acid and pour into a glass beaker and add in 3 spatulas of copper oxide powder
gently heat for a few minutes but make sure it does not boil as it produces poisonous fumes
stir with glass rod so the copper oxide can dissolve and leave to cool
pour the solution into a different beaker and clean graphite rods with sand paper
connect the rods to the power pack with leads and clips
plug in DC use 6v
pass electricity through solution for two minutes
