Solution-xA0-Reactions are-SO3-2-x2212-H2SO4-SO2SO2-K2Cr2O7-H2SO4-Cr2-SO4-3SO2 is colourless gas with irritating smellCr2-SO4-3 is green colour solutionX - -SO3-2-x2212-Y-SO2The correct option is A

$[X] + H_{2} S O_{4} \to [Y]$ ; a colourless gas with irritating smell
$[Y] + K_{2} C r_{2} O_{7} + H_{2} S O_{4} \to$ Green solution $[X]$ and $[Y]$ are:
$S^{2 -}, H_{2} S$
$S O_{3}^{-}, S O_{2}$
$C O_{3}^{2 -}, C O_{2}$
$C l^{-}, H C l$

Solution
Reactions are
$(S O_{3})^{2 -} + H_{2} S O_{4} = S O_{2}$
$S O_{2} + K_{2} C r_{2} O_{7} + H_{2} S O_{4} = C r_{2} (S O_{4})_{3}$
$S O_{2}$ is colourless gas with irritating smell
$C r_{2} (S O_{4})_{3}$ is green colour solution
X = $(S O_{3})^{2 -}$
Y= $S O_{2}$
The correct option is A

[X]+H2SO4→[Y]; a colourless gas with irritating smell[Y]+K2Cr2O7+H2SO4→ Green solution [X] and [Y] are:S2−,H2SSO−3,SO2CO2−3,CO2Cl−,HCl

Solution Reactions are(SO3)2−+H2SO4=SO2SO2+K2Cr2O7+H2SO4=Cr2(SO4)3SO2 is colourless gas with irritating smellCr2(SO4)3 is green colour solutionX = (SO3)2−Y=SO2The correct option is A

$[X] + H_{2} S O_{4} \to [Y]$ ; a colourless gas with irritating smell
$[Y] + K_{2} C r_{2} O_{7} + H_{2} S O_{4} \to$ Green solution $[X]$ and $[Y]$ are:
$S^{2 -}, H_{2} S$
$S O_{3}^{-}, S O_{2}$
$C O_{3}^{2 -}, C O_{2}$
$C l^{-}, H C l$

Solution
Reactions are
$(S O_{3})^{2 -} + H_{2} S O_{4} = S O_{2}$
$S O_{2} + K_{2} C r_{2} O_{7} + H_{2} S O_{4} = C r_{2} (S O_{4})_{3}$
$S O_{2}$ is colourless gas with irritating smell
$C r_{2} (S O_{4})_{3}$ is green colour solution
X = $(S O_{3})^{2 -}$
Y= $S O_{2}$
The correct option is A
