Cations Nat, Pb2+, Ag+, Ni²+, Cr3, Zn, Mg2+ Keep track of any descriptions. (e.g. NP First do Na is green) flame test Then add source I of Cl(e.g. HCI) Supernatant (solution) Solid precipitate i.e. ppt or P Ni?", Cr3+, Zn²+, Mg2+ PbCl2, AgCl Hot H2O Solid Try adding stuff to see what Solution happens!! (Follow your lab manual) Pb2+, Cl- Na2SO4 l or Nal PbSO4 Pbl2 ppt white ppt Very yellow AgCl (white) Figure 4 Qualitative Analysis 130
