Vedclass · Answer

(B) The red coloured mixed oxide $(X)$ is $Pb_3O_4$ (red lead).When $Pb_3O_4$ reacts with conc. $HNO_3$,it forms lead$(II)$ nitrate and lead$(IV)$ oxide $(PbO_2)$,which is compound $(Y)$:$Pb_3O_4 + 4HNO_3 \rightarrow 2Pb(NO_3)_2 + PbO_2 + 2H_2O$$PbO_2$ (compound $Y$) reacts with $HCl$ to produce lead$(II)$ chloride $(PbCl_2)$,which is compound $(Z)$:$PbO_2 + 4HCl \rightarrow PbCl_2 + Cl_2 + 2H_2O$$Pb_3O_4$ (compound $X$) also reacts with conc. $HCl$ to produce $PbCl_2$ (compound $Z$):$Pb_3O_4 + 8HCl \rightarrow 3PbCl_2 + Cl_2 + 4H_2O$Thus,$(X), (Y),$ and $(Z)$ are $Pb_3O_4, PbO_2,$ and $PbCl_2$ respectively.

$A$ red coloured mixed oxide $(X)$ on treatment with conc. $HNO_3$ gives a compound $(Y).$ $(Y)$ with $HCl$ produces a chloride compound $(Z)$ which can also be produced by treating $(X)$ with conc. $HCl.$ Compounds $(X),$ $(Y),$ and $(Z)$ will be
