Identify the spectator ions for the reaction that occurs when aqueous solutions of lithium sulfide and copper(II) nitrate are mixed to form the insoluble copper(II) sulfide. a. Li+ and NO3- b. No spectator ions are present. c. Li+ and Cu2+ S2- and d. Cu2+ Cu2+ and NO3-

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
