A hydrate is ANY substance that forms a stable substance with water.
for example:
CaCl2•2H20 is calcium chloride dihydrate
These form are not necessarily soluble in water in fact it is not until
CaCl2•6H20 that this compound exhibits solubility in water.

Hydrate is a term which means different things in inorganic chemistry and organic chemistry. To put it simply, it just means that whatever you have contains water.
In organic chemistry, a hydrate is a compound formed by the addition of water to a host molecule. Thus ethanol could be considered to be the hydrate of ethylene. These substances do not contain water as such, but have their constituents (hydrogen, oxygen, hydroxyl) so arranged that water may be eliminated. Hence, hydrates are derivatives of, or compounds with, hydroxyl.
In inorganic chemistry, hydrates contain water molecules that are either bound to a metal center or crystallized with the metal complex. Such hydrates are also said to contain "water of crystallization" or "water of hydration".

In the oil & gas industry, "hydrate" refers to methyl hydrate, a combination of methane and water in an ice-like form. It is troublesome in that it can block openings or cause mechanisms to become jammed.
