I am getting confused on this concept. Everywhere says that Common Ions decrease solubility. Yet in this problem,
Ksp of PbCl2 is 1.6x10-5. What is the solubility of PbCl2 in .01 M KCl?
The solubility is .16 M. So wouldn't that mean that common ions make the solubility increase?
Question: Is benzophenone more soluble in MetOH or Hexane?
Answer: Benzophenone dissolves faster in MetOH than in Hexane.
Benzophenone is a ketone, making it polar, but majorly nonpolar with two phenyl rings.
If we would put these in terms of fractions, I would say that this molecule is 3/4...
Question: What is the reason why methylene chloride is miscible in Hexane?
My reasoning is #2 below:
Methylene Chloride is a polar molecule due to the 2 dipole-dipole interactions bonds (C-Cl) -|->
Hexane is a nonpolar molecule due to the dispersion/london/vdw forces.
