Etymology Origin:
The word "anhydrous" originates from Greek roots, combining an- (negation) and hydor (water), with the suffix -ous to form an adjective. It literally means "without water," reflecting its scientific use to describe substances devoid of water molecules, either naturally or through chemical processes. The term has been used in chemistry since the early 19th century to distinguish dry compounds from their hydrated forms.
The anhydrous form of the compound is more stable at high temperatures.
Chemists often store anhydrous solvents in sealed containers to prevent moisture absorption.
