CdF2 (s) Cd²+ (aq) + 2 F- (aq)
1. A saturated solution of CdF2 is prepared. The equilibrium in the solution is represented above. In the
solution [Cd²+] eq = 0.0585 M and [F-] eq = 0.117 M.
a. Determine the solubility of CdF2.
b. Some 0.90 M NaF is added to the saturated solution. Does the solubility of CdF2 increase,
decrease, or remain the same? Justify your answer based on Q.
2. Is the solubility of AgCl(s) greater in distilled water or in tap water where the [CI-] = 0.010
your answer based on Q.
