The aqueous solution of a certain compound (X), when added to a copper sulphate solution, a brown precipitate is obtained which tums white on addition of excess of `Na_(2)S_(2)O_(3)` solution. Its aqueous solution, when added to `Ag^(+)` ion solution, a yellow curdy precipitate is obtained which is insoluble in ammonium hydroxide. Hence, compound (X) is

A

NaBr

B

KBr

C

Kl

D

To solve the problem step by step, we need to analyze the information provided and deduce the identity of compound (X). ### Step 1: Analyze the first reaction with copper sulfate - The problem states that when the aqueous solution of compound (X) is added to a copper sulfate solution, a brown precipitate is formed. - This brown precipitate is likely to be cuprous iodide (CuI), which is known to form when iodide ions react with copper(II) ions. ### Step 2: Identify the brown precipitate - The brown precipitate that is formed can be identified as cuprous iodide (CuI). This is consistent with the formation of a brown precipitate when iodide ions are present in the solution. ...
