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?

  • $\begingroup$ 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. $\endgroup$ – Ivan Neretin Mar 1 '16 at 15:17
