Work Sheet 7 —More Solubility Equilibria 1. A solution is made with NaI and NaCl such that it is 0.01 M in both I - and Cl - . To 1 L of this solution 0.01 moles Cu(NO 3 ) are added (you can ignore any volume change). The NaI, NaCl, and Cu(NO 3 ) are completely soluble (as is NaNO 3 but you already knew that). The K SP for CuI is 1.3 x 10 -12 and for CuCl is 1.0 x10 -6 . After the solution has reached equilibrium what are the concentrations of the following? [Cu + ] [I - ] [Cl - ] Are there any solid precipitates? If so how many grams of each. 2. The K sp of PbCl 2 is 1.7 x 10 -5 . How many grams of PbCl 2 will dissolve in 100 mL of a 0.1 M NaCl solution? 3. Will CaF 2 be more soluble in acid or base? 4. Consider the following reactions AgCN(s) --- Æ Ag + (aq) +

### What students are saying

• 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.
