A white solid imparts a violet colour to a Bunsen flame. On being heated with concentrated `H_(2)SO_(4)`, the solid gives violet vapours that turn starch paper blue. The salt may be :

A salt when heated with H_(2)SO_(4) librates violet gas which turns starch paper blue, salt may be

A salt, which on heating with conc. H_(2)SO_(4) gives violet vapour is

A salt , which on heating with conc. H_(2)SO_(4) gives violet vapour is

Does KI salt on heating with concentrated H2SO4 ,Evolves coloured vapours?

A whiite crystalline salt imparts a violet colour to a Bunsen flame, and with hot concentrated H_(2)SO_(4) , forms a pungent gas. On treatment with an AgNO_(3) solution, this gas forms a white precipitate readily soluble in NH_(3) . The whiite crystalline salt may be:
