    Jul 03, 2018· When gold deposits on the Zn surface, it packs tightly. To deposit gold, you must dissolve some zinc. Therefore, when the zinc is completely covered with gold, it stops depositing and the zinc stops dissolving. You end up with gold coated pieces of zinc. Unless you used a lot of zinc, most of the gold is still in solution.
