Iodine is sparingly soluble in pure water. However, it does 'dissolve' in solutions containing excess iodide ion because of the following reaction: 1(aq) + 12(aq) = 13(aq) K = 710. For each of the following cases calculate the equilibrium ratio of [13] to [12]. 5.00x10-2 mol of I2 is added to 1.00 L of 5.00x10-1 M KI solution. 3.20x102 You are correct. Previous Tries The solution above is diluted to 12.50 L. 7.09 Submit Answer You have entered that answer...

5. How does protonation change the structure of carbonate? (adding an H+to CO32- ) 6. Sulfur dioxide and carbon dioxide have somewhat different properties, in spite of the fact that both are triatomic molecules with two terminal oxygen atoms. Can you explain why they are as different as they are? 7. Because carbon tetrachloride is not soluble in water, a test tube containing the two liquids will form two layers. Predict which layer is on top and justify your answer....

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
