Learning Objectives 2/21/08 You should: 1. know how to calculate decreases in the solubility of ionic compounds resulting from the common ion effect . 2. be able to predict how changes in pH will affect the solubility of ionic compounds. 3. understand why complex ion formation enhances the solubility of ionic compounds and know how to determine the solubility of an ionic compound in the presence of a complexing agent. Common Ion Effect The solubility of a salt will decrease in the presence of a common ion (one of the ionic participants in the solubility equilibrium). Consider the insoluble salt SrF 2 SrF 2 H s L F Sr 2 + H aq L + 2 F - H aq L Addition of the soluble salt NaF (F - is the common ion) will suppress the dissolution of SrF 2 . According to LeChatelier’s Principle, addition of one of the products in the equilibrium reaction will shift equilibrium toward reactants reducing the amount of SrF 2 dissolved. 2 In the previous lecture we calculated the solubility of SrF 2 and found that it was 8.6 ä 10 - 4 M. Find the solubility of SrF 2 in a solution that also contains 0.1 M of the soluble salt NaF.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
