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...

1. As the new chemist working at "Drugs Us", you are given the task of resolving racemic phenylethyl- amine into its individual enantiomers using (S)-malic acid as resolving agent. After you carried out the resolution, you labeled the products you isolated "Sample A" and "Sample B. You subjected both samples to polarimetry ( = 589 nm (sodium D-line), 1-dm cell) and obtained the following results. Sample A: 1.00 g dissolved in 10.0 mL methanol...
