An inorganic salt when heated evolves colured gas which bleaches moist litmus paper. The evolved gas is :

A

`NO_(2)`

B

`SO_(2)`

C

`N_(2)O`

D

`I_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Some nitrates on heating give `NO_(2)` which bleaches moist litmus paper due to its oxidizing nature.

An inorganic salt when heated with concentrated H_(2)SO_(4) evolves a colourless pungent smelling gas but with concentrated H_(2)SO_(4) " and" MnO_(2) , evolves a cxoloured pungent smelling gas which bleaches moist litmus paper. The coloured gas is :

A sodium salt (A) is heated with cone. Sulphuric acid. The evolved gas truns moist litmus paper red and producess white fumes in contact with a glass rod moistened with ammonia solution. It also gives white precipitate when passed through AgNO_(3) solution. When the salt is heated with MnO_(2) and cone. H_(2)SO_(4) , a gas with an irritating smell is evolved which turns starch-iodide paper blue. Identify the salt and the gaseous product evolved from it. Explain your answer with relevant chemical equations.
