Compared with Fig. 8, Cr and Mn do not respond to the addition of chlorine, whereas Cu, Zn, Ni and Pb are affected by the chlorides at different levels. Pb displays the greatest response to the addition of chlorine: at 400 K, Pb reacts with Cl and gaseous substances form, such as volatile PbCl 4 (g), PbCl 2 (g) and PbCl(g).
