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 Rome, where the children, Eugene and Julius were born. The family relocated to Venice when Karl became professor at the Academy of Venice. Eugene de Blaas art was well received in England, he exhibited regularly at the Royal Academy, the Grafton Gallery and the New Gallery. 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
