# Rationalise the given statements and give chemical reactions Lead (II) chloride reacts with Cl _ 2 to give PbCl _ 4.

11.13.    Rationalise the given statements and give chemical reactions :

(a)  Lead (II) chloride reacts with  $Cl_{2}$ to give $PbCl_{4}$.

$Pb$ is belong to the group 14th and it has two oxidation states +2 and +4. On moving down the group, the stability of the +2 oxidation state is more than the +4 oxidation state, it is due to the inert pair effect. This $PbCl_{4}$ is less stable than $PbCl_{2}$. However, the formation of $PbCl_{4}$ takes places when the chlorine gas is bubbled by a saturated solution of $PbCl_{2}$.
$PbCl_{2}+Cl_{2}\rightarrow PbCl_4$
