Calculate the molar solubility of CaF_2 at 25degreeC in a solution of 0.010 M NaF. The...
The mineral fluorite is calcium fluoride, CaF_2. The goal is to calculate the molar solubility of CaF_2 in water from its solubility product constant (k_sp=3.4 times 10^-11). Write down the ICE chart: Write down K_sp in terms of the solubility (s) and solve for s. The goal now is to calculate solubility after adding 0.15 MCaCl_2. Write down the new ICE chart and solve for the new s.
