Answer:
Ag+ (aq) + Cl- (aq) → AgCl (s)
Step-by-step explanation:
The reaction between silver nitrate and sodium chloride is a double displacement reaction, where silver cations (Ag+) from silver nitrate react with chloride anions (Cl-) from sodium chloride to form solid silver chloride (AgCl) precipitate.
The balanced chemical equation for this reaction is:
AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)
To write the net ionic equation, we need to eliminate the spectator ions (ions that do not participate in the reaction). In this case, the sodium cation (Na+) and the nitrate anion (NO3-) are spectator ions because they appear unchanged on both sides of the equation.
The net ionic equation for the reaction is:
Ag+ (aq) + Cl- (aq) → AgCl (s)
This equation shows that silver cations (Ag+) and chloride anions (Cl-) react to form solid silver chloride (AgCl) precipitate, which is responsible for the cloudy appearance of the solution.
