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
The Orissa (Alteration of Name) Act, 2011 for the word Orissa, the word Odisha shall be substituted. The Orissa (Alteration of Name) Act, 2011 The Orissa (Alteration of Name) Act, 2011 is an Act of Odisha Legislative Assembly to alter the name of State of Orissa by substituting Orissa with Odisha. Due to decolonization during British rule, names of several states and cities have been changed. Of late, basing on the demands of the civil society the government of Odisha decided to revert the names to its original ones. The Constitution of India and several other legal documents were drafted with the changed names for which it
