RE: PbWO4 (stolzite) solubility product?
Lange's Handbook of chemistry (McGraw Hill) gives the following solubility products:
RE: PbWO4 (stolzite) solubility product?
Nevertheless, the information I had in hand for Ksp of PbWO4 is a much lower value --> ten to the minus 30 sth.
Also, I have seen other reference mentioning its Ksp in the magnitude of ten to the minus eleven.
I am really confused which one is the correct value on earth.
Could you please provide any additional information? I really really appreciate your great help.
Thank you again.
RE: PbWO4 (stolzite) solubility product?
I cannot provide more help, only the suggestion that the reason for the discrepancies may be that tungstates and molybdates tend to form polyanions of the kind HW6O215- and their salts with metal cations, having smaller solubility products.
