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
Water law in the United States motion determined that the state did not have proper standing to proceed with this case without the Cherokee Nation's involvement. Water project law is the branch of state and federal law that deals with the construction, management, financing, and repair of major water projects, including public drainage, irrigation, flood control, navigation and other projects. Some of these projects are constructed and managed by state and local government. But many are constructed and managed by special local improvement districts, which are special political subdivisions of state government. Water project law has had, and continues to have, a significant role in the
