Order solubility of PbI2
0.010 NaI < 0.010 Pb(NO3)2 < H2O = Ba(NO3)2 = KNO3
NaI and Pb(NO3)2 have common ion effect on the solubility of PbI2. They will suppress the solubility of PbI2. The solSolubil of PbI2 depends upon more on I- ( 2x2) as compare to Pb2+ (x). So in NaI has less solubility as compare to Pb(NO3)2 while H2O, Ba(NO3)2 and KNO3 don't have any effect on solubility of PbI2.

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
