(B) In qualitative analysis,$(NH_4)_2CO_3$ is used as the group reagent for the $5^{th}$ group cations,which include $Ba^{2+}$,$Ca^{2+}$,and $Sr^{2+}$.The chemical reaction for the precipitation of $Ba^{2+}$ is:$Ba^{2+} + (NH_4)_2CO_3 \rightarrow BaCO_3 \downarrow + 2NH_4^{+}$Thus,$Ba^{2+}$ is detected by obtaining a white precipitate of barium carbonate $(BaCO_3)$.
