How do we predict if a metal will be dissolved in a solution?

A metal will dissolve in the solution if the standard cell potential of the redox reaction is positive, meaning the standard Gibbs free energy is negative because that would mean the reaction is spontaneous.

Proceed about problem as normal; find E(nought) and plug into Nernst. If deltaG is positive the rxn is nonspont and thus the metal won't dissolve. If deltaG is negative the rxn is spont and thus the metal will dissolve.
