Rationalize the given statements and give chemical reactions : Lead (II) chloride reacts with Cl_2 to give PbCl_4.

Answer»

Solution : Lead belongs to group 14 of the periodic table. The two oxidation states displayed by this group is +2 and +4. On moving down the group, the +2 oxidation state becomes more stable and the +4 oxidation state becomes LESS stable. This is because of the inert pair effect. Hence, `PbCl_4` is much less stable than `PbCl_2`. HOWEVER, the formation of `PbCl_4` TAKES place when chlorine gas is bubbled through a saturated solution of `PlCl_2`.
`PbCl_(2(s)) + Cl_(2(G)) to PbCl_(4(l))`
