Calcium Complexing and the Enhanced Solubility of Gypsum in Concentrated Sodium-Salt Solutions1
- F. S. Nakayama2
Solubility of Gypsum in NaClO4, NaCl, NaNO3, and NaOAc solutions and their mixtures was determined experimentally and theoretically. The dissociation constants of CaCl+, CaNO3+, CaOAc+, NaOAc0, and NaNO30 were computed from the solubility behavior of the solid. The predicted solubility values corresponded closely to the measured values in mixed Na-salt solutions when allowances were made for Ca-complexing.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
