I. The molar solubility of salt: The solubility of salt AnBm is defined as: S=one [A^m+] = one [B^n-]. Calculating s from Ksp.
1a) Calcualte the solubility of Ca3(PO4)2 in water. (Ksp=1.0x10^-26).
1b) Try CaF2
II. Solubility and the common ion effect:
1) Qualitative Approach: How is the solubility of CaF2 in water different from its solubility in Ca(NO3)2? Is CAF2 more or less soluble in water than Ca(NO3)2?
2) Quantitative Approach: Calculate the solubility of CAF2 in a 0.15 M solution of Ca(NO3)2.
III. Criterion for Precipitation
1) 2.0 L of a 0.050-M Pb(NO3)2 solution is mixed with 5.0 L of a 0.050-M NaCl solution. Will PbCl2 precipitate? (Ksp of PbCl2 is 1.6x10^-5).
