Desiccation



 

Desiccation is the state of extreme dryness, or the process of extreme drying. A hygroscopic substance that induces or sustains such a state in its local vicinity in a moderately-well sealed container.

Science

 

Desiccator

In science, a sodium hydroxide, is placed below the shelf.

Often some sort of humidity indicator is included in the desiccator to show, by color changes, the level of humidity. These indicators are in the form of indicator plugs or indicator cards. The active chemical is Anhydrous cobalt chloride is blue. When it bonds with two water molecules, (CoCl2•2H2O), it turns purple. Further hydration results in the pink hexaaquacobalt(II) chloride complex [Co(H2O)6]2+.

Biology and ecology

In biology and ecology, desiccation refers to the drying out of a living organism, such as when aquatic animals are taken out of water, or when plants are exposed to sunlight or drought. Ecologists frequently study and assess various organisms' susceptibility to desiccation.

Broadcasting

In broadcast engineering, a desiccator may be used to pressure also keeps water or other dampness from coming in the line at any point along its length.
