can zinc chloride or zinc sulphate used as electrolyte in the voltaic cell in order to determine the potential difference between two different metal that act as electrode......the electrode used is cooper and zinc?????

You can use either zinc chloride or zinc sulfate for the zinc compartment, and any soluble copper salt for the copper compartment.
Sulfates are usually preferred to chlorides, because they often give salts that can be weighed out more accurately (definite hydrates), and because they don't complex as readily with ions in solution, which would affect the cell potential.

You can refer to the reduction-potential table, if you can see zinc chloride or zinc sulphate coupled with copper then the answer is yes.
