Transition-Metal Complexes (Section)
Crystals of hydrated chromium(lll) chloride are green, have an empirical formula of CrC13 • 6 H20. and are highly soluble, (a) Write the complex ion that exists in this compound, (b) If the complex is treated with excess AgN03(sq), how many moles of AgCI wfl precipitate per mole of CrC13 • 6 H20 dissolve in solution? (c) Crystals of anhydrous chromium(lll) chloride are violet and insoluble in aqueous solution. The coordination geometry of chromium in these crystals is octahedral as is almost always the case for Cr3+. How can this be the case if the ratio of Cr to Cl is not 1:6?
