Tests for Ammonium Ion

Element not present in Nessler’s reagent is

Nessler's reagent does not have :

Name a colourless cation not a representative element.

Write the probable colour of the ammonium salts?

How do you test aluminium ions?

A colourless water soluble solid $\text{'}\mathrm{X}\text{'}$ on heating gives equimolar quantities of $\mathrm{Y}$ and $\mathrm{Z}$ . $\mathrm{Y}$ gives dense white fumes with $\mathrm{HCl}$ and $\mathrm{Z}$ does so with ${\mathrm{NH}}_3.\mathrm{Y}$ gives brown precipitate with Nessler's reagent and $\mathrm{Z}$ gives white precipitate with nitrates of ${\mathrm{Ag}}^{+},{\mathrm{Pb}}^{2+}$ and ${\mathrm{Hg}}^{+}·\text{'}\mathrm{X}\text{'}$ is:

The pungent smell produced in the reaction of ammonium ions with $\mathrm{NaOH}$ is due to the formation of 

Write the chemical equation for the identification of ammonium ion using sodium hydroxide solution.

Sodium hydroxide cannot be used to identify :

Alkaline solution of mercuric iodide is known as Nessler's reagent.

When ammonia gas is passed through Nessler's solution the colour becomes-

Complete the following reaction:

${\mathrm{NH}}_4\mathrm{Cl}+\mathrm{NaOH}\stackrel{∆}{\to }$

What is the correct statement about product in the following reaction?
${\mathrm{K}}_2\left[\mathrm{H}\mathrm{g}{\mathrm{I}}_4\right]+\mathrm{N}{\mathrm{H}}_4\mathrm{C}\mathrm{l}+\mathrm{K}\mathrm{O}\mathrm{H}\to \underset{(\mathrm{B}\mathrm{r}\mathrm{o}\mathrm{w}\mathrm{n}\mathrm{ }\mathrm{p}\mathrm{p}\mathrm{t}.)}{\mathrm{P}\mathrm{r}\mathrm{o}\mathrm{d}\mathrm{u}\mathrm{c}\mathrm{t}}$

A compound (A) on heating with an excess of caustic soda solution liberates a gas (B) which gives white fumes on exposure of $\mathrm{HCl}$. 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:

On passing a gas, '$X$', through Nessler's reagent, a brown precipitate is obtained. The gas '$X$ ' is

Nesseler's reagent gives brown colour with

Select the incorrect statement.

Nessler's reagent is used to detect

$\left(\text{X}\right)\stackrel{\text{KOH}}{\to }\left(\text{Y}\right)(gas\; turns\; red\; litmus\; blue)+\left(\text{Z}\right)\stackrel{\text{Zn}+\text{KOH}}{\to }\left(\text{Y}\right)(gas).$

$\left(\text{X}\right)\stackrel{\text{Δ}}{\to }\text{gas}(does\; not\; support\; combustion)$

Identify (X) to (Z):

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 $H{g}_2^{2+}$. 'X' is :
