Assignment:
The fluoride ion is very toxic. Not only does it interfere with glycolysis, but if forms an insoluble precipitate with calcium ions (Ksp = 4.13 x 10-11). Give an explanation as to why CaF2 is insoluble; whereas, other calcium halides are soluble in the order CaI2>CaBr2>CaCl2. How much fluoride (as sodium fluoride) would you have to ingest to cause the precipitation of CaF2 in blood. Assume that the blood level of calcium is 2.50 x 10-3 M and that there is a total of 5.00 L of blood in the person.
Provide complete and step by step solution for the question and show calculations and use formulas.
