Passage - I :

Brown gas 'B' is

A

`H_(2)S`

B

`NH_(3)`

C

`NO_(2)`

D

All of these

Text Solution

Verified by Experts

`S+underset((A))(6HNO_(3))to underset((aq))(H_(2)SO_(4))+underset((B))(6NO_(2(g)))+2H_(2)O`
`underset((A))(Na_(2)SO_(3))+S to underset((C ))(Na_(2)S_(2)O_(3))`
`underset((C ))(Na_(2)S_(2)O_(3))+2HCl to 2NaCl+SO_(2)+S+H_(2)O`
`therefore A=` sulphur , `B=NO_(2)` (Reddish Brown Gas) : `C=Na_(2)S_(2)O_(3)` (Hypo) , `D=SO_(2)` (Colour less gas) , E = Sulphur (PPT)
