Q. A salt on treatment with dil. HCl gives a pungent smelling gas and a yellow precipitate. The salt gives green flame when tested. The salt solution gives a yellow precipitate with potassium chromate. The salt is

$N i S O_{4}$

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

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

$C u S O_{4}$

$B a^{+ 2} + 2 C H_{3} CO O^{-} \to (C H_{3} COO)_{2} B a$

$B a S_{2} O_{3}$ gives $S O_{2}$ gas with dil. $H Cl$ and also yellow ppt. of Barium chromate.

$(C H_{3} COO)_{2} B a + K_{2} C r O_{4} \to 2 C H_{3} COO K + (yellow ppt.) B a C r O_{4} ↓$
