i forgot :0 :0 :0....lol just kiddin ...here u go :

use supluric acid....

CuO + H2So4 = CuSo4 + H2

take dilute sulphuric acid in a beaker and add excess of copper(ll)oxide so that all the acid gets used up.heat and mix this solution wth a glass rod... when the bubbles of gas start coming out (which is hydrogen) this shopws the reaction has ended

filter the solution to remove any excess copper oxide then:

evaporate the solution to the point of crystallisation and u will obtain crystals of copper sulphate.
