Dodecahydrate

/ˌdɒdɪkəˈhaɪdreɪt/ noun

Definition

A chemical compound that contains twelve molecules of water combined with another substance.

Etymology

From 'dodeca-' (twelve) and 'hydrate,' derived from Greek 'hydro' (water). In chemistry, the prefix indicates the number of water molecules in the crystalline structure.

Kelly Says

Chemists use these numbers like a recipe—'dodecahydrate' tells you exactly how much water is locked into a crystal, which determines the compound's color, hardness, and when it will crumble into dust.
