... AuCl (Ksp = 2x10-13) MnCO3 (Ksp = 2.3x10-11) PbCrO4 (Ksp = 2.8x10-13) Since they are all the same number of pieces, you can compare them directly by K sp values. Thus: AuCl (Ksp = 2x10-13) < PbCrO4 (Ksp = 2.8x10-13) < MnCO3 (Ksp = 2.3x10-11) < NiCO3 (Ksp = 1.4x10-7) 10. Put the following substances ...
