The term "anhydro-" is a prefix used in chemistry to denote the absence of water or the removal of water from a compound. Anhydrous compounds are those that have had their water of crystallization removed, resulting in a more concentrated and often more reactive form of the substance. This prefix is commonly found in the names of various chemicals, such as anhydrous sodium sulfate or anhydrous calcium chloride, which are used in a wide range of industrial and laboratory applications due to their enhanced properties compared to their hydrated counterparts.
