Compounds that produce the same number of ions
CuS Ksp = 8.5x10-45
Ag2S p = 1.6 * 10 - 49
Bi2S3 p = 1.1 * 10 - 73
3. Calculate the solubility of solid CaF2 ( sp=4.0*10. ) in a 0.025 M NaF solution.
Write the solubility equilibria and solubility product expressions for the following:
a. Ag2CO3
b. Ca3(PO4)2
2 answers
Ca3(PO4)2 ==> 3Ca^2+ + 2PO4^3-
Ksp = [Ca^2+]^3[PO4^-3]^2
Ksp is the produce of the concentrations and raise each to the power indicated by the coefficient.
The Ag2CO3 is done the dame way.
For the last question note that the first one is the ONLY one with equal ions.
CuS ==> Cu^2+ + S^2-
Ag2S and Bi2S3 do not produce equation ions.
