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....

Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...
