Question:

Once you have separated the three salts in Study Question 111 into three test tubes, you now need to confirm their presence.
(a) For Pb2+ ion, one way to do this is to treat a precipitate of PbCl2 with K2CrO4 to produce the bright yellow insoluble solid, PbCrO4. Using Ksp values, confirm that the chloride salt should be converted to the chromate salt.KCRO4 added Stirred PbCl precipitate White PbCl is converted to yellow PbCrO4 on adding KCrO4. Cengage

Data given in Question 111

You have a solution that contains AgNO3, Pb(NO3)2, and Cu(NO3)2. Devise a separation method that results in having Ag+ in one test tube, Pb2+ in another, and Cu2+ in a third test tube. Use solubility guidelines and Ksp and Kf values.
