Water of crystallization degree of hydration can be critical to the resulting chemical properties. For example, anhydrous RhCl is not soluble in water and is relatively useless in organometallic chemistry whereas RhCl•3HO is versatile. Similarly, hydrated AlCl is a poor Lewis acid and thus inactive as a catalyst for Friedel-Crafts reactions. Samples of AlCl must therefore be protected from atmospheric moisture to preclude the formation of hydrates. Crystals of hydrated copper(II) sulfate consist of [Cu(HO)] centers linked to SO ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water. A fifth water resides elsewhere
In the Water In the Water In the Water () is an oil on cradled panel painting of a skinny dipping young woman by Eugene de Blaas. This painting is the only nude picture created by de Blaas, as all his other subjects are fully clothed. It is 78.4 cm high and 44.5 cm tall. The painting depicts a naked young woman standing up to mid-calf in water, leaning forward, looking down at a school of tiny fish. She has a rosy complexion, and her curly, dark brown hair is tied back. Although there is no sun in the composition, golden light shines
