Question

(a)  If the molar solubility of CaF2 at 35 oC is 1.24 x 10-3 mol/L, what is the Ksp at this temperature? 

 

(b)  It is found that 1.1 x 10-2 g of SrF2 dissolves per 100 mL of aqueous solution at 25 oC.  Calculate the solubility product for SrF2? 

 

 

(c)  The Ksp of Ba(IO3)2 at 25 oC is 6.0 x 10-10.  What is the molar solubility of Ba(IO3)2? 

 

 

(d)  Answer this question without using any other resources.  In part (a), what would the Ksp value of CaF2 be, if it was measured at 25 oC instead of 35 oC?
