Lecture 19 At-home practice Which factor had the effect of decreasing the solubility (compared to all the other factors which increase solubility)? 1. A sample of PbSO4 solid has reached equilibrium in a beaker of water. If the ionic strength of the solution is then increased by adding LINO3 salt, what happens to the activity coefficients of the Pb2 and SO,2 ions? What happens to the solubility of the PbSO4? 2. Which of these four salts will...

Solubility Product For the following questions, identify the ions comprising the salt, and then use the expression for the solubility product to perform the necessary calculations. This simple exercise involves the assumptions that you can ignore any complications which might result as a consequence of the basicity or acidity of the ions, ion pairing, complex ion formation, or auto-ionization of water. Calculate the concentration, in mol/L, of a saturated aqueous solution of Cag(PO4)30H (Ksp = 6.80x10-37). mol/L 1 pts Submit...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

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...
