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
Wading in the Water Wading in the Water Wading in the Water is a 2007 mixed media collage by artist India Cruse-Griffin located on the Eskenazi Health campus, near downtown Indianapolis, Indiana, and is part of the Eskenazi Health Art Collection. "Wading in the Water" is a 2007 mixed media collage by artist India Cruse-Griffin, which depicts a young woman in a pink dress in front of a tree-lined bank, waist deep in a body of water, reaching down to grab a fish. The work, which measures 37.25" x 49.25", framed, is made from collaged paper gathered from magazines, upon which Cruse-Griffin then paints,
