Question

$NaCl_(aq)$ gives a white precipitate with $AgNO_{3}$ solution but $CCl_{4}$ or $CHCl_{3}$ does not, because

• A. $NaCl$ is a covalent compound and forms $AgCl$ as white ppt
• B. $NaCl$ is an ionic compound and forms $AgCl$ as white ppt
• C. $CCl_{4}$ and $CHCl_{3}$ are ionic compound
• D. none of these

Answer 1

Answer: (B)

$NaCl$ is an ionic compound and forms $AgCl$ as white ppt

Answer 2

$NaCl$ being an ionic compound and thus reacts with $AgNO_{3}{(aq)}$ to give ionic reaction, forming $AgCl$ as white ppt. $CCl_{4}$ and $CHCl_{3}$ being covalent do not furnish $Cl^{-}$ ions in solution. $NaCl + AgNO_3\rightarrow AgCl + NaNO_3$
