A groundwater is in contact with the mineral fluorite (CaF2(s)), which dissolves to yield Ca2+ and F according to the following expression: CaF2(s) = Ca2+ + 2 F- (Ks0 of 3 x 10-11) (a) ( What are the aqueous solubilities (S) of CaF2(s), Ca2+, and F-for this system (assuming no Ca+ or F are initially present)? (b) ) Would the amount of Ca2+ and F-that can dissolve into the water from CaF2(s) be higher, lower, or the same compared to the S values calculated in part (a) if some Ca2+ and F were are already present in the groundwater? Why? (c) Now, assume that the groundwater initially contained [Ca2+] = 0.1 mM and [F-] = 0.2 mM, and you wanted to determine how much additional Ca2+ and F. (if any) could dissolve into the water from the CaF2(s). Set up an expression that would allow you to determine these values. Note: You only need to set up the expression, but do not need to solve it. Hint: You might find the CaSO4(s) examples in the precipitation/dissolution lecture notes helpful here, but be sure to account for the differing stoichiometries of Ca2+ and F-in this reaction
