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
What the Water Gave Me (painting) What the Water Gave Me (painting) What the Water Gave Me ("Lo que el agua me dio" in Spanish) is an oil painting by Frida Kahlo that was completed in 1938. It is sometimes referred to as What I Saw in the Water. Frida Kahlo’s "What the Water Gave Me" was her biography. As the scholar, Natascha Steed, points out, "her paintings were all very honest and she never portrayed herself as being more or less beautiful than she actually was." With this piece she reflected on her life. Kahlo released her unconscious mind through the use of what seems
