A precipitate of ' X ' would be obtained on adding HCl to a solution of $Sb_{2} S_{3}$ in YAS(yellow ammonium sulphide)

Answer:

Solution:

$S b_{2} S_{3} + 2 (N H_{4})_{2} S_{2} ⟶ Sb_{2} S_{5} + 2 (N H_{4})_{2} S$

$S b_{2} S_{5} + 3 (N H_{4})_{2} S ⟶ 2 (N H_{4})_{3} S b S_{4}$

$2 (N H_{4})_{3} S b S_{4} + 6 H Cl ⟶ S b_{2} S_{5} ↓ + 6 N H_{4} Cl + 3 H_{2} S$
