In this video we grow crystals of pure silver metal by electochemistry.

The procedure is fairly simple. Just apply an electric current between a silver anode and an aluminum or silver metal cathode while they are immersed in silver nitrate solution. The silver ions from the anode will deposit on the cathode.

The crystals are microscopic so to see them the solution is placed under a microscope. A glass slide may be placed over the solution to keep the surface flat so you can see it better.

The crystals grow in different shapes depending on concentration and current applied.
