A colourless water soluble solid (X) on ...

A colourless water soluble solid (X) on heating gives equimolar quantities of (Y) and (Z). Y gives dense white fumes with HCl and Z does so with `NH_(3)`. Y gives brown ppt. with `K_(2)Hgl_(4)` (Nesslers reagent) and Z gives white precipitate with nitrates of `Ag^(+), Pb^(2+) and Hg^(+)`. What is X ?

Text Solution

AI Generated Solution

To solve the problem, we need to analyze the information given about the colorless water-soluble solid (X) and the products (Y and Z) formed upon heating. ### Step-by-Step Solution: 1. **Identify the Nature of Solid (X)**: - The solid (X) is colorless and water-soluble. This suggests it could be an ammonium salt, as many ammonium salts are colorless and soluble in water. 2. **Heating of Solid (X)**: ...
