Question

${\text{AgNO}}_3\text{(aq)}+\text{NaCl}\text{(aq)}\to \text{AgCl}\text{(s)}+{\text{NaNO}}_3\text{(aq)}$

Above reaction is an example(s) of:

• A. Combination reaction
• B. Precipitation reaction
• C. Decomposition reaction
• D. Double displacement reaction

Answer 1

Answer: (B), (D)

The correct options are
B Precipitation reaction
D Double displacement reaction

The reaction in which exchange of ions takes place between the compounds of the reactants is called double displacement reaction.
Often, a precipitate forms in a double displacement reaction. In the given reaction both ${\text{AgNO}}_3$ and $\text{NaCl}$ are exchanging their ions to form new compounds and a precipitate of $\text{AgCl}$ is formed. Hence, the given reaction is an example of double displacement and precipitation reaction.
