Why is a Dessicator important?
Let's review. Desiccators are important for drying reactants prior to their use in chemical reactions. They are usually sealed air-tight to prevent water vapor from entering, and contain a desiccant in order to absorb any water vapor that does enter the chamber.Jan 26, 2016
Where is a desiccant used?
Desiccants induce dryness in any environment and reduce the amount of moisture present in air.
