Ferricyanide Crystal

General Procedure

The most general way to grow a crystal includes forming a supersaturated solution by heating up water and adding in the crystal medium, here I used Potassium Ferricyanide, until is doesn't dissolve anymore.

For a general procedure, the following link can be used: How to Grow a Potassium Ferricyanide Crystal

The following is the procedure that I followed:

1. Obtain potassium ferricyanide, a 250 mL beaker, a stirplate/hotplate, and a stirbar.
2. Begin heating up the water on the hotplate and add the stirbar.
3. Once hot, begin adding the potassium ferricyanide (It will take some time for it to dissolve, but it eventually will).
4. Keep adding until the rate of dissolution decreases( The article above mentions to use about 93g in 200mL of water).
5. Cover the finished solution with something(a watchglass or parafilm) and let it sit overnight.
