A white precipitate was formed when BaCl2{BaCl}_{2} was added to water extract of an inorganic salt. Further, a gas ′X′' X ' with characteristic odour was released when the formed white precipitate was dissolved in dilute HCI. The anion present in the inorganic salt is:A white precipitate was formed when BaCl _ 2 was added to water extract of an inorganic salt. Further, a gas ' X ' with

Options

  1. AI−{I}^{-}
  2. BSO32−{{SO}_{3}}^{2 -}
  3. CS2−{S}^{2 -}
  4. DNO2−{NO}_{2}^{-}

Correct answer

B. SO32−{{SO}_{3}}^{2 -}

Step-by-step solution

A white precipitate was formed when BaCl _ 2 was added to water extract of an inorganic salt. Further, a gas ' X ' with

A white precipitate was formed when BaCl2{BaCl}_{2} when added to water extract of SO3−2{SO}_{3}^{- 2} salt. which is an inorganic salt.whitepracipitateofBaSO3whitepracipitateof{BaSO}_{3} is formed. Further, a gas SO2{SO}_{2} with burning sulphur like odour will be released when theBaSO3{BaSO}_{3} is dissolved in dilute HCI.
