Question

Describe the steps involved in preparing Copper Chloride from CuO and HCl

Answer 1

Copper chloride can be made simply by diluting some copper(II)oxide in  Hydrochloric acid. The black CuO compound quickly dissolves in the colorless HCl to form a solution of green colored CuCl2.
The equation that takes place is as follows:

        CuO + 2HCl -------> CuCl2 + H2O 
          (s)       (aq)             (s)           (l)

However, the tricky part is usually making CuCl2 from copper. This is since copper does not react with non-oxidizing acids like HCl or dilute sulphuric acid. So you can't use copper directly with the HCl. First you have to convert the Cu to CuO.
-you need to acquire the CuO to use in the step with HCl as above.
-CuO can be made from the reaction of sodium hydroxide and CuSO4.
-Or you could burn copper dust which will give you copper(II)oxide directly.

Answer 2

dissolve solid copper oxide in some amount ofdil hydrochloric acid . dissolve it completely heat if required , now  boil the solution untill the vvolume decreases to half of original volume , now leave the mixture for slow cooling with out disturbing it . crystals of copper chloride will be separated at the bottom of the container which can be taken out by filtration . The reaction is 
CuO + HCl ----> CuCl2 +  H2O
