Vedclass · Answer

(A) The reaction of solid salts with dilute $H_2SO_4$ is a standard qualitative analysis test for anions:$1$. $CO_3^{2-}$ reacts with dil. $H_2SO_4$ to release $CO_2$ gas,which causes effervescence $(A-II)$.$2$. $S^{2-}$ reacts with dil. $H_2SO_4$ to release $H_2S$ gas,which has the smell of rotten eggs $(B-III)$.$3$. $Cl^{-}$ (in some cases like $NaCl$ with conc. $H_2SO_4$ or specific conditions) can release $Cl_2$ gas (yellowish-green,pungent) if an oxidizing agent is present,but in standard qualitative analysis,$Cl^-$ is identified by the evolution of $HCl$ gas. However,based on the provided options,$C$ matches with $IV$ $(Cl^-)$ and $D$ matches with $I$ $(NO_2^-)$ which releases brown fumes of $NO_2$ gas.Therefore,the correct matching is $A-II, B-III, C-IV, D-I$.

List-$I$ Solid salt treated with dil. $H_2SO_4$	List-$II$ Anion detected
$A.$ Effervescence of colourless gas	$I.$ $NO_2^-$
$B.$ Gas with smell of rotten egg	$II.$ $CO_3^{2-}$
$C.$ Yellowish green gas with pungent and suffocating smell	$III.$ $S^{2-}$
$D.$ Brown fumes	$IV.$ $Cl^{-}$
