« on: September 27, 2015, 09:22:52 PM »
I am looking to electrolysis of magnesium sulphate using copper electrodes please could anyone predict the products formed?I will use 9 volts of current

Have you consulted reduction potential tables? What are ions present in the solution?

Sorry, that's not how the forum works. You have to do your legwork first. Any general chemistry book will teach you basic knowledge about electrolysis - please read it and come here when you have detailed questions.

More detailed informations to check:

Is magnesium electrolysis in water possible? Do you know a condition for a metal to deposit from an aqueous solution?

Do copper electrodes participate in electrolysis? There is one known example with sulphate. Is copper a good choice at all?

What are typical voltages for electrolysis? Hint: they resemble one-cell battery voltages, since both result from the same values. Do 9V single-cells exist?
