Question

A white powder soluble in NH 4 OH but insoluble in water is (A) BaSO 4 (B) CuSO 4 (C) PbSO 4 (D) AgCl

Tardigrade Admin · Accepted Answer

AgCl is a covalent compound hence it is insoluble in water also it form complex with NH 4 OH, thus is soluble in NH 4 OH AgCl +2 NH 4 OH → [ Ag ( NH 3)2] Cl + H 2 O

Q. A white powder soluble in $N H_{4} O H$ but insoluble in water is

$B a S O_{4}$

$C u S O_{4}$

$P b S O_{4}$

AgCl

$A g Cl$ is a covalent compound hence it is insoluble in water also it form complex with $N H_{4} O H$ , thus is soluble in $N H_{4} O H$
$A g Cl + 2 N H_{4} O H \to [A g (N H_{3})_{2}] Cl + H_{2} O$
