Solubility Product Constant: Ksp
18. Aqueous Equilibrium / Solubility Product Constant: Ksp / Problem 4
Copper ions can be used to disinfect swimming pools. It is advised to use a concentration of roughly 0.2 ppm. To maintain this concentration, a slightly soluble salt can be added to the pool. What is the concentration of Cu+ in parts per million that is in equilibrium with CuCl (Ksp = 1.7×10–7)?
