How to grow crystals with salt: To use chemical reactions between water and potash alum(Potassium) in the creation of various crystal formations.
Crystals consist of an orderly arrangement in the molecular structure of a solid object, this pattern known as crystallinity.
Crystals can be man-made by heating water with a chemical known as potash alum. Many geometrical shapes can be created through this process, such as cubic, hexagonal, tetragonal crystals.
Important notice: parental or teacher guidance required for all process.
When Rochelle salt (Potassium sodium tartrate )mixture is Supersaturated, the atoms will form patterns of crystals.
what is rochelle salt: Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of tartaric acid first prepared (in about 1675) by an apothecary, Pierre Seignette, of La Rochelle, France. Potassium sodium tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity. Wikipedia
You should begin to notice the growth process of tiny crystals inside the small glass cup. Remove fragments of crystals using the tweezers. Place them on a paper towel and allow to dry.
The crystals will continue to increase in size within the glass cup. Count the number of crystals you can create. What shapes are they? Record your results.
Crystals grow from supersaturated solutions. Crystals rely on their nourishment from outside material. When the atoms of the mixture reach the surface they form in an orderly pattern. This orderly patterned is referred to as a crystal.
