webmaster Posted December 26, 2004 Share Posted December 26, 2004 From: Allan Treiman Subject: Ksp for Crocoite? Could you help me track down the solubility product for Crocoite, PbCrO4. This ought to be easy, but--- 1. The 1986 thermo0.com data base gives log(Ksp) = -12.73 while the newer thermoRev7b gives log(Ksp) -12.087. Both databases refer to the same paper for these numbers. 2. Literature values range from log(Ksp) = -13.66 through -12.19 (and even higher in older literature). 3. Several sources on the web give a value of log(Ksp) = -13.75, e.g., Ksp = 1.77E-14, but without a citation. Can anyone please 1) refer me to the source of the -13.75 value, and/or 2) aim me at a critical review of the thermochem of PbCrO4? Quote Link to comment Share on other sites More sharing options...
