Hydrate, any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight. Washing soda is efflorescent, which means it loses some of its water molecules at room temperature. The prefix is determined by the number of water molecules in the hydrate which is itself determined by the salt. A Comprehensive Guide. The presence of hydrates is quite purposeful in the three fields of endeavour. A few of them are: Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the composition without indicating how the water is bound. For hydrate chemistry names, the salt's name is written out first, then a prefix depending on the number of water molecules, then the word "hydrates.". X-ray diffraction studies have shown that hydrated beryllium sulfate (BeSO4∙4H2O) and hydrated beryllium nitrate (Be(NO3)2∙4H2O) both contain the tetrahedral complex ion [Be(H2O)4]4+. One of the most commonly used is gypsum CaSO4*2H2O which is used for "dry wall". All of these are inorganic hydrates. The dot separating the $CaCl_2$ from the two water molecules isn't a multiplication symbol. You then add the word "hydrate" to the prefix to give the complete hydrate name.
