Consider a groundwater saturated with respect to PbSO4 (Ksp= 1.7*10^-8) mixing with a groundwater saturated with respect to CaSO4 (Ksp=10^-5). Assume a 50:50 mixture between the waters such as 500mL of each water mixing to form a 1.0L solution

a. What is the saturation index (SI) of each mineral in the final solution

b. Will precipitation occur?

c. If precipitation does occur, what is the mass of the precipitated material?
