Explanation:

i,Take a beaker filled with water and add a few drops of dilute sulphuric acid.

Heat the water. ...

During this process stir continuously.

Continue adding copper sulphate powder till no more powder can be dissolved.

Filter the solution.

Leave it for cooling.

Slowly, the copper crystals will separate out.

ii,Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize. This is used to separate these two compounds.

iii,Copper turnings from a mixture of copper turnings and iron filings
