NO_(2)^(Theta) interferes to the icingTest of NO_(3)^(Theta)suggest a chemicalmethodof removed burned with a blue flame initial but isputoff uinstandly even as gas appear coming Example. c. While testingoxalate, gas obtained burns with a blue flame intially but is put off instantly even as gas appears coming. Explain. d. I^(Theta) also interfere in the 'Ring Test' of NO_(3)^(Theta) suggest a chemicalreagent that removed I^(Theta) e. Colourless of (A)overset(Delta) to(B) gas + (C ) gas aquens solution of (c ) turn restlitrman blue , aquerous solutionof (A) and (B) also give while ppt , with AgNO_(3) solutionsouble in aqneous solutionof (C ) identify (A) ,(B) and (C ) f. Can youy defect Br^(Theta) and I^(Theta) by layer if present together ?

SOLUTION :`AgI lt AgBr lt AgCI lt AgF`
b. Boll the mixture `NH_(4)O_(2)^(Theta)` is decomposed as `N_(2)`
`NaNO_(2) + NH_(4)CI OVERSET(Delta) to NaCI + N_(2) uarr + 2H_(2)O`
c. `H_(2) C_(2)O_(4) overset(Delta) toH_(2)O_((1)) + CO_(2(g))`
d. `HgCI_(2)` removes `I^(Theta)`as `HgI_(2)`
`HgCI_(2) + 2I^(Theta) rarr underset("ORANGE ppt")(HgI_(2) uarr + 2CI^(Theta)) `
e. (A) `NH_(4)CI (B): HCI (C ): NH_(3)`
f. Reducin g power `I^(Theta) gt Br^(Theta) gt CI^(Theta) gt F^(Theta)` ADD `CI_(2)` and `CHCI_(3)` into mixture of `I^(Theta)` and `Br^(Theta)`
`2I^(Theta) CI_(2) rarr underset("Violet")(I_(2) +) 2CI^(Theta)`
`2Br^(Theta) + CI_(2) rarr underset("Orange yellow")(Br_(2)) + 2CI^(Theta)`
`Br^(Theta)` will be also oxides `I^(Theta)` to `I^(Theta)` .Thus first there will be violetcolour in `CGCI_(3)` layer Extract aq layer (containing `Br^(Theta))` and repeat adding `CI_(2)` water and `CHCI_(3)` orange -yellow colour in `CHO_(3)` layer condifirms `Br^(Theta)`
