Chemistry 211 REVIEW Problems from Solubility and Volumetric Analysis. This is your first Chemistry 211 assignment. These problems are relatively simple equilibrium problems involving solubility, weak acids, and principles of volumetric analysis. You should be capable of doing them already. If you need to review, have a look at chapters 6 and 7 in Harris. If you are having a lot of trouble solving these, don't worry at this stage – we will touch on most of the questions as time passes in the course. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1. This is a “simple” solubility equilibrium problem. The solubility of a salt is defined as the number of moles of the salt that dissolve per liter of solvent. Calculate the molar solubility of Ag 2 CrO 4 in: a. water b. 0.050 M Na 2 CrO 4 solution c. 0.050 M AgNO 3 solution Data: K sp (Ag 2 CrO 4 ) = 1.2 X 10 -12 (see Appendix F – Solubility Products) 2. An important part of analytical chemistry is separating mixtures for subsequent analysis. This
