In this simple chemistry demonstration or crystal project you'll grow a silver crystal tree. This is a variation of the classic method of growing silver crystals on a copper wire or bead of mercury.

Silver Crystal Tree Materials

  • sheet of copper that has been cut into a tree shape or a tree made from copper wire
  • 0.1 M silver nitrate solution

Grow a Silver Crystal Tree

How It Works

2 Ag+ + Cu → Cu2+ + 2 Ag

When you are finished growing the silver crystals, you can remove the tree from the solution and use it as a decoration.
