Vedclass · Answer

(A) complex gives a white precipitate with $BaCl_2$ if it contains ionizable sulfate ions $(SO_4^{2-})$ in the coordination sphere.In the complex $[Cr(NH_3)_5Cl]SO_4$,the $SO_4^{2-}$ ion is present outside the coordination sphere.When this complex reacts with $BaCl_2$,it undergoes the following reaction:$[Cr(NH_3)_5Cl]SO_4 + BaCl_2 \rightarrow [Cr(NH_3)_5Cl]Cl_2 + BaSO_4 \downarrow$ (white precipitate).Therefore,option $A$ is correct.

Formula	Moles of $AgCl$ precipitated per mole of the compound with excess $AgNO_3$
$(i) PdCl_2 \cdot 4NH_3$	$2$
$(ii) NiCl_2 \cdot 6H_2O$	$2$
$(iii) PtCl_4 \cdot 2HCl$	$0$
$(iv) CoCl_3 \cdot 4NH_3$	$1$
$(v) PtCl_2 \cdot 2NH_3$	$0$
