Calcium chloride is quite soluble, whereas the solubility product of calcium fluoride, CaF 2 , is only 3.9 ? 10 -11 . A waste stream of 1.00 ? 10 -3 M HCl is injected into a formation of limestone, CaCO 3 , where it comes into equilibrium. Give the chemical reaction that occurs and calculate the hardness and alkalinity of the water at equilibrium. Do the same for a waste stream of 1.00 ? 10 -3 M HF.
