hydrate

Chemical compound that has discrete water molecules combined with it. The water is known as water of crystallization and the number of water molecules associated with one molecule of the compound is denoted in both its name and chemical formula: for example, CuSO4.5H2O is copper(II) sulphate pentahydrate.

Even compounds that are normally gaseous can form solid hydrates under certain conditions. For example, there are large amounts of methane (natural gas) stored at the bottom of the oceans in the form of solid methane hydrate.
