$S^{2-}(aq.)$

Vedclass · Answer

(D) $BaCl_2$ forms precipitates with anions that produce insoluble barium salts. $AgNO_3$ forms precipitates with anions that produce insoluble silver salts.$(a)$ $CO_3^{2-}$ forms $BaCO_3$ (precipitate) and $Ag_2CO_3$ (precipitate).$(b)$ $C_2O_4^{2-}$ forms $BaC_2O_4$ (precipitate) and $Ag_2C_2O_4$ (precipitate).$(c)$ $MnO_4^{-}$ does not form a precipitate with $BaCl_2$ or $AgNO_3$ as both $Ba(MnO_4)_2$ and $AgMnO_4$ are soluble in water.$(d)$ $S^{2-}$ does not form a precipitate with $BaCl_2$ ($BaS$ is soluble),but it forms $Ag_2S$ (black precipitate) with $AgNO_3$.Thus,$S^{2-}$ is the correct answer.

Column-$I$	Column-$II$
$(P) NaBr + \text{conc. } H_2SO_4 \rightarrow$	$(A) \text{Colourless gas}$
$(Q) Na_2S + \text{dil. } HCl \rightarrow$	$(B) \text{Brown colour}$
$(R) NaNO_2 + \text{dil. } HCl \rightarrow$	$(C) \text{Rotten smell}$
$(S) NaNO_3 + \text{conc. } H_2SO_4 \rightarrow$	$(D) \text{Paramagnetic}$

Which of the following anions does not produce a precipitate with $BaCl_2$ solution,however,gives a precipitate with $AgNO_3$?
