One of the more common hydrates is copper(II) sulfate pentahydrate, which contains 5 moles of water per 1 mol of copper(II) sulfate, written as CuSO4·5H2O. It is used as a catalytic ... 1. In an experiment, 2.3754 g of copper(II) sulfate pentahydrate is heated to drive off all the water of crystallization.

Hydrate Lab Purpose The objective of this experiment is to determine the number of moles of water associated with one mole of copper sulfate, Salts that contain water as part of their crystal structure are called hydrates (or hydrated salts) and the water in the crystal structure is called the water of hydration.

Glauber's salt is sodium sulfate decahydrate, Na2SO4·10H2O. Crystals of it readily give up their water of crystallization at ordinary temperatures, forming a powdery coating of the anhydrous salt; this phenomenon (efflorescence) is exhibited by many hydrates.

Dictionary: water of crystallization ... Historically, the structures of many hydrates were unknown, ... Crystals of the aforementioned hydrated copper sulfate consist of [Cu(H2O)4]2+ centers linked to SO42- ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water.

It is this ease of crystallization that is the bane of natural chalcanthite crystals, at least with respect to mineral collectors. More often than not, excellent crystals for sale from mineral dealers are fakes or more specifically, artificially grown crystals from a solution of copper sulfate in someone's house or shop.
