The equation AgNO$_3$(aq) + NaCl(aq) $\longrightarrow$ AgCl$\downarrow$ + NaNO$_3$(aq) uses a downward arrow for AgCl. What does this indicate?
AAgCl escapes as a gas
BAgCl is present in aqueous solution
CAgCl forms as an insoluble precipitate
DAgCl requires heating to form
Answer & Solution
Correct answer: C. AgCl forms as an insoluble precipitate
1. A downward arrow $\downarrow$ replaces the solid state symbol (s) when the product is an insoluble solid.
2. Such an insoluble solid that separates out is called a precipitate.
3. A gaseous product would carry an upward arrow $\uparrow$, so 'escapes as a gas' is wrong.
4. Aqueous state is shown by (aq) and heating by $\Delta$, so the aqueous and heating options are wrong.
