Tests for Iodide Ion

What is silver nitrate test?

The following equation represents double displacement reaction, what is the precipitate formed in this reaction?

${\mathrm{AgNO}}_3\left(\mathrm{aq}\right) + \mathrm{NaI}\left(\mathrm{aq}\right) \to \mathrm{AgI}\left(\mathrm{s}\right) + {\mathrm{NaNO}}_3\left(\mathrm{aq}\right)$

Describe the test of iodide ion in presence of dilute nitric acid and silver nitrate solution, followed by the addition of dilute ammonia solution and then concentrated ammonia solution.

Describe the concentrated sulphuric acid test for iodide ion.

Select the test that is used to detect the presence of iodide ions.

When ${\mathrm{CS}}_2$ layer containing both ${\mathrm{Br}}_2$ and ${\mathrm{I}}_2$ is shaken with excess of ${\mathrm{Cl}}_2$ water, the violet colour due to ${\mathrm{I}}_2$ disappears and a pale yellow colour appears in the solution. The disappearance of violet colour and appearance of pale yellow colour is due to the formation of :

Ozone when reacts with potassium iodide solution liberates certain product, which turns starch paper blue. The liberated substance is.......

$....... .$ is formed when potassium iodide is heated with conc. ${\mathrm{H}}_2{\mathrm{SO}}_4$

When $C{l}_2$ water is added to a salt solution containing chloroform, chloroform layer turns violet. Salt contains

A salt gives violet vapours when treated with conc. $H_{2}S{O}_4$ . It contains

Starch can be used as an indicator for the detection of traces of

Starch-iodide paper is used to test the presence of-

When a white solid ($\mathrm{X}$) reacts with concentrated ${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$ , the products include pungent smelling gases and a dark brown solution containing a yellow precipitate. When aqueous solution of thiosulphate is added, the precipitate remains but the dark brown colour disappears. The compound '$\mathrm{X}$' is
