The fоllоwing аniоns cаn be sepаrated by precipitation as lead salts: OH-, I–, CrO42–, AsO43- . If Pb2+ is added to a solution containing the four anions (each anion at a concentration of 0.10 M) in what order will they precipitate?   First, [I] Second, [II] Third, [III] Fourth, [IV]   Compound Ksp PbCrO4= 1.8 x 10–14 Pb3(AsO4)2= 4.1 x 10–36 Pb(OH)2= 2.8 x 10–16 PbI2= 8.7 x 10–9
