Drying and dehydrating agents


Drying agent

A drying agent is a chemical used to remove water from an organic compound that is in solution. 


Dehydrating agent

A dehydrating agent is a substance that dries or removes water from a material. In chemical reactions where dehydration occurs, the reacting molecule loses a molecule of water. Sulfuric acid, concentrated phosphoric acid, hot aluminum oxide, and hot ceramic are common dehydrating agents in these types of chemical reactions.
