Vedclass · Answer

(B) The salt is $BaS_2O_3$ (Barium thiosulfate).$1$. Reaction with dil. $HCl$: $BaS_2O_3 + 2HCl 	o BaCl_2 + SO_2 \uparrow + S \downarrow$. The $SO_2$ gas has a pungent smell,and the sulfur $(S)$ forms a yellow precipitate.$2$. Flame test: $Ba^{2+}$ ions impart a grassy green color to the flame.$3$. Reaction with potassium chromate: $Ba^{2+} + K_2CrO_4 	o BaCrO_4 \downarrow + 2K^+$. $BaCrO_4$ is a yellow precipitate.

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