1) The solubility of NaNO3 in water increases as temperature increases. What can we say about ∆H and ∆S from this information only?
2) What is the molar solubility of Pb(IO3)2 in water at 25 0 C? The Ksp of Pb(IO3)2 is 2.5 x 10-13.
3) In these experiments, how can you verify the solution analyzed was saturated?
4) In the virtual world here, we neglect other subsequent equilibria that can influence solubility. What other equilibria could be important to consider in the real world for the solubility of Ca3(PO4)2 and Ag2SO4?
