How are single electrode potential and potential of metal with respect to vacuume related?

Question

When a metal rod (say zinc) is dipped in a solution of it's salt (say 1 molar zinc sulphate), what would be the work done in bringing a unit positive charge from infinity to the metal?

Would the potential (i) in the bulk of the rod, (ii) on the surface of the rod, (iii) in the solution which is at 0.05 nm away from solution and (iv) in the bulk of the solution be calculate?

Can we assign absolute potential values for all these 4 regions? If yes, what would be their values?

Answer 1

I think this is your assignment young man! Where is your teacher? I'm gonna tell her about this...

Answer 2

Vaccum or not you should see no appreciable change in potential.
