# Galvanic cell of copper and zinc

When we dip zinc metal in zinc sulfate solution, does zinc sulfate ionize into Zn and sulfate ions? Zinc ions come into the solution as Zn$^{+2}$ so why is the metal not completely dissociated?

Why is zinc sulfate used as an electrolytic solution?

• Basically, this is because we want to know the concentration on $\ce{Zn^2+}$ to plug it into the Nernst equation. The galvanic cell would work just as well with pretty much any other electrolyte. – Ivan Neretin Mar 1 '16 at 15:17
