Important Questions on Inorganic Qualitative Analysis

EASY
What colour is formed in the reaction of ammonia with Nessler’s reagent? 
EASY
Which element is not present in Nessler’s reagent?
EASY
When ammonia gas is passed through Nessler's solution the colour becomes-
HARD
X KOH Y (gas turns red litmus blue) + Z Zn + KOH Y (gas) .

X Δ gas (does not support combustion)

Identify (X) to (Z):
EASY
Alkaline solution of mercuric iodide is known as Nessler's reagent.
EASY
When ammonia gas is passed through Nessler's solution the colour becomes-
HARD
A white crystalline solid 'A' on boiling with caustic soda solution gives a gas 'B' which on passing through an alkaline solution of potassium tetraiodomercurate (II) solution gives a brown ppt. The substance 'A' on heating evolves a neutral gas 'C', which is inert at room temperature and reactive in the presence of catalyst and does not give brown fumes with nitric acid oxide.

The gas 'C' is
MEDIUM
In Nessler's reagent for the detection of ammonia, the active species is:
MEDIUM
When an ammonium salt is warmed with a sodium hydroxide solution, ammonia gas is evolved. State three ways in which you could identify this gas.
MEDIUM

Complete the following reaction:

NH4Cl+NaOH

HARD
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 NH3. Y gives brown precipitate with Nessler's reagent and Z gives white precipitate with nitrates of Ag+, Pb2+ and Hg22+. 'X' is :
EASY
Alkaline solution of mercuric iodide is known as Nessler's reagent.
HARD

A compound (A) on heating with an excess of caustic soda solution liberates a gas (B) which gives white fumes on exposure of HCl. The resultant alkaline solution thus obtained after heating again liberates the same gas (B) when heated with zinc powder. Compound (A) on heating alone gives a neutral oxide of nitrogen not nitrogen gas. Choose the correct statement from the following:

EASY
The number of iodine atoms in one formula unit of Nessler's reagent is ------.
EASY
What is the correct statement about product in the following reaction?
K2[HgI4]+NH4Cl+KOHProduct(Brown ppt.)
