Desiccant Types

Indiing silica gel is a silica gel bead or granule that has been washed with a concentration of cobalt chloride ( a heavy metal salt). The cobalt chloride is a deep blue color when it is dry and turns from blue to purple to pink as it becomes saturated with moisture. Typically, the color changes as the desiccant goes past 8% moisture levels

In analyses of metal ions detection of the endpoint is mainly based on substances that change color when creating complexes with determined metals. An example of such indiors is Eriochrome Black T, substance used at pH between 7 and 11. It is blue when free, and red-orange when forming complex with a metal ion.

Color of chemicals - Wikipedia

01.08.2003· The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths.This spectral perspective was first noted in atomic spectroscopy.
