anhydride

Oxide minus moisture

An anhydride is a chemical compound formed by removing water from another compound, especially an acid.

Acid anhydrides result when two acid molecules combine with the loss of water: acetic anhydride, sulfur dioxide as the anhydride of sulfurous acid.

The term appears primarily in chemistry contexts, describing compounds that yield acids when water is added back.
