BaS 2 O 3 gives out SO 3 gas along the with colloidal sulphur on reaction with dil. H 2 SO 4 . Ba 2+ gives green flame and forms yellow ppt. with potassium chromate.

Q. A salt on treatment with dil. $H Cl$ gives a pungent smelling gas and a yellow precipitate. The salt gives green flame test and a yellow precipitate with potassium chromate the salt is

$N i S O_{4}$

$B a S_{2} O_{3}$

$P b S_{2} O_{3}$

$C u S O_{4}$

$B a S_{2} O_{3}$ gives out $S O_{3}$ gas along the with colloidal sulphur on reaction with dil. $H_{2} S O_{4} . B a^{2 +}$ gives green flame and forms yellow ppt. with potassium chromate.
