Assuming potassium thiocyanate completely dissociates in aqueous solution, find the Initial Concentrations of SCN- in the reaction mixture?
The maximum allowable concentration of Pb2+ ions in drinking water is 0.05 ppm (i.e., 0.05 gof Pb2+ in 1 million grams of water). (a) What is the Pb2+ concentration of an underground water supply at equilibrium with the mineral galena (PbS) (Ksp = 3.4 ×10−28) ?
(b) Does this concentration exceed the allowable concentration guideline?
