Question

$NaC{l}_{\left(aq\right)}$ gives a white precipitate with $AgN{O}_3$ solution but $CC{l}_4$ or $CHC{l}_3$ does not, because:

• A. $NaCI$ is a covalent compound and forms $AgCl$ as white ppt
• B. $NaCl$ is an ionic compound and forms $AgCl$ as white ppt
• C. $CC{l}_4$ and $CHC{l}_3$ are ionic compound
• D. none of these

Answer 1

The correct option is B $NaCl$ is an ionic compound and forms $AgCl$ as white ppt

$NaCl$ being an ionic compound and thus reacts with $AgN{O}_3\left(aq\right)$ to give ionic reaction, forming $AgCl$ as white ppt. $CC{l}_4$ and $CHC{l}_3$ being covalent do not furnish $C{l}^{-}$ ions in solution.
$NaCl+AgN{O}_3\to AgCl+NaN{O}_3$
