In aqueous solution cobalt(II) ion is surrounded by 4 water molecules and has a light pink color. When high concentrations of chloride ion are introduced, a cobalt-chloride complex ion forms that has a distinctive blue color. One way to represent this equilibrium is: Cocl,"(aq) = Co2+ (aq) + 4 CI" (aq) An experiment was run to demonstrate that a dynamic equilibrium exists between these two ions. Starting with a special form of CoC142(aq) where one of the chloride ions was...

Section Name Experiment 12 Advance Study Assignment: The Alkaline Earths and the Halogens I. As pure clements, all of the halogens are diatomic molecular species, Their melting points are: F,, 54 K: Br 266 K; and I, 387 K. Using the Periodic Table, predict as best you can the molecular Cl., 172 1 formula of elemental astatine, At, the only radioactive element in this family. Also predict whether it will be a solid, liquid, or gas at rOom temperature. Elemental...

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
