Question

The correct match of the group reagents in List-I for precipitating the metal ion given in List-II from solutions, is

	LIST - I		LIST - II
(P)	Passing $H_{2} S$ in the presence of $NH_{4} OH$	(1)	$Cu^{2 +}$
(Q)	$(NH_{4})_{2} CO_{3}$ in the presence of $NH_{4} OH$	(2)	$Al^{3 +}$
(R)	$NH_{4} OH$ in the presence of $NH_{4} Cl$	(3)	$Mn^{2 +}$
(S)	Passing $H_{2} S$ in the presence of dilute HCl	(4)	$Ba^{2 +}$
		(5)	$Mg^{2 +}$
