4. Solid calcium iodate, Ca(IO3)2, (MW = 389.9 g/mol) is only slightly soluble in cold water. Measurements indicate that only 0.12 g of the compound dissolve for every 100 ml of solution at 5C. Write the dissolution equation, the K expression, then determine the value of the equilibrium constant for calcium iodate dissolving in water at 5C.

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,...
