Questions: Enter the balanced complete ionic equation for the reaction AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) Express your answer as a complete ionic equation including phases.

Solution Steps

The given reaction is: \[ \mathrm{AgNO}_{3}(\mathrm{aq}) + \mathrm{NaCl}(\mathrm{aq}) \rightarrow \mathrm{AgCl}(\mathrm{s}) + \mathrm{NaNO}_{3}(\mathrm{aq}) \]

In aqueous solutions, soluble ionic compounds dissociate into their respective ions. Therefore, we write the dissociation of the aqueous compounds:

• \(\mathrm{AgNO}_{3}(\mathrm{aq})\) dissociates into \(\mathrm{Ag}^{+}(\mathrm{aq})\) and \(\mathrm{NO}_{3}^{-}(\mathrm{aq})\).
• \(\mathrm{NaCl}(\mathrm{aq})\) dissociates into \(\mathrm{Na}^{+}(\mathrm{aq})\) and \(\mathrm{Cl}^{-}(\mathrm{aq})\).
• \(\mathrm{NaNO}_{3}(\mathrm{aq})\) dissociates into \(\mathrm{Na}^{+}(\mathrm{aq})\) and \(\mathrm{NO}_{3}^{-}(\mathrm{aq})\).

Substitute the dissociated ions into the equation, keeping the solid compound \(\mathrm{AgCl}(\mathrm{s})\) intact because it does not dissociate:

\[ \mathrm{Ag}^{+}(\mathrm{aq}) + \mathrm{NO}_{3}^{-}(\mathrm{aq}) + \mathrm{Na}^{+}(\mathrm{aq}) + \mathrm{Cl}^{-}(\mathrm{aq}) \rightarrow \mathrm{AgCl}(\mathrm{s}) + \mathrm{Na}^{+}(\mathrm{aq}) + \mathrm{NO}_{3}^{-}(\mathrm{aq}) \]
