#400-Ksp, Solubility Constant
POSTLAB

1. How would an increase in temperature affect the Ksp value obtained for
Calcium Iodate?





Given the Ksp for CaCO3: Ksp = 8.7 x 10 -9

2. Give the solubility equilibrium reaction between the solid and its
ions in solution (be sure to label the phases.)




3. Give the solubility product expression




4. Calculate the solubility in mol/L of CaCO3. (Think about the
relationship between the products and reactant in part A)








5. Calculate the solubility from part C in grams/L.
