A) a soluble sulphate
B) \[KBr\] or \[NaBr\]
C) \[Ba{{(N{{O}_{3}})}_{2}}\]
D) \[AgN{{O}_{3}}\]
Correct Answer: D
Solution :
Since the powder gives brown fumes, it must be a bromide or nitrate. Since, its solution gives yellow ppt. with KI and white ppt. with \[BaC{{l}_{2}}\] it must be \[AgN{{O}_{3}}\]. \[AgN{{O}_{3}}+KI\xrightarrow{\,}\underset{Yello}{\mathop{AgI}}\,\,\,+KN{{O}_{3}}\] \[2AgN{{O}_{3}}+BaC{{l}_{2}}\xrightarrow{\,}\underset{\text{White}\,\text{ppt}\text{.}}{\mathop{\,2AgCl}}\,+Ba{{(N{{O}_{3}})}_{2}}\]You need to login to perform this action.
