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
Timeline of the Greater Victoria Water System manage to fill a single Beaker in the Harbour.” But for all its other advantages, Camosack, which became Fort Victoria, had the same problem. Lieutenants Warre and Vavason of the Royal Engineers noted on their inspection of the place in 1845: “This fort has lately been established; it is badly situated with regard to water and position, which latter has been chosen for its agricultural advantages only.” Of course the newly established Fort Victoria could not exist without a water supply. Exploration of the surrounding area located two sources, both about east of the fort at what became known as
