WebI would say it would decrease solubility of CaF2 (CaF2 <---> Ca2+ + 2F-). In solution F- ions react with water bay this reaction: F- + H2O <--> HF + OH- adding a base, this reaction is moved to the right, increasing the concentration of F- ions which moves upper reaction to right, favoring precipitate formation 2 comments ( 2 votes) Show more... WebSep 27, 2024 · How do I calculate the simultaneous solubility of the above mentioned salts given that: Let the solubility of C a F X 2 be x and that of S r F X 2 be y. Dividing the two we get, x = 0.013 y Substituting this value of x in equation 1, I got y = 5.2 × 10 − 3 which should be the solubility of S r F X 2. However, answer given is 9 × 10 − 4 M ...

Webon fluorspar (CaF2). The process generally used is to react 93 to 99 percent sulfuric acid and pulverized acid grade fluorspar (calcium fluoride). The reaction occurs in a heated rotary kiln at a controlled tem-perature for approximately 30 to 60 minutes. The reaction products are hydrogen fluoride gas and calcium sulfate.
