Vedclass · Answer

(B) $1$. The salt must contain $Cl^-$ ions to form a white precipitate of $AgCl$ with $AgNO_3$. This eliminates option $D$.$2$. The salt must contain $Ba^{2+}$ ions to form a white precipitate of $BaSO_4$ with dilute $H_2SO_4$. This eliminates options $A$ and $C$.$3$. $BaCl_2$ contains both $Cl^-$ and $Ba^{2+}$ ions.$4$. $Ba^{2+}$ ions impart a characteristic apple-green color to the flame in the flame test.$5$. Therefore,$BaCl_2$ is the correct salt.

Which of the following salts gives a white precipitate with $AgNO_3$ and dilute $H_2SO_4$,and also gives a green flame test?
