Identify the following type of reaction.
NaC1 (aq) + AgNO₃ (aq) AgC1(s) + NaNO₃ (aq)

Correct option is D

The correct answer is: (D) Double displacement reaction

In the given reaction:

$$\text{NaCl (aq)}+\text{AgNO₃ (aq)}\to \text{AgCl (s)}+\text{NaNO₃ (aq)}$$

• NaCl (aq) is an aqueous solution of sodium chloride, and AgNO₃ (aq) is an aqueous solution of silver nitrate.
• The reaction involves the exchange of ions between the two reactants, leading to the formation of a precipitate (AgCl) and the remaining ions staying in aqueous form.
• This is a double displacement reaction because the ions of one compound exchange with the ions of another to form two new products.

• Double displacement reactions occur when two ionic compounds react in aqueous solution, resulting in the exchange of ions and the formation of precipitate, gas, or water.
