Double Displacement Reaction Example:

One example of a double displacement reaction is the reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) to form silver chloride (AgCl) and sodium nitrate (NaNO3).

The chemical equation for this reaction is:

NaCl + AgNO3 → AgCl + NaNO3

Explanation:

In a double displacement reaction, two ionic compounds exchange ions to form two new compounds. In this example, NaCl and AgNO3 are both ionic compounds, and they react to form two new compounds, AgCl and NaNO3.

- Sodium chloride (NaCl) is a white crystalline compound that contains sodium ions (Na+) and chloride ions (Cl-).
- Silver nitrate (AgNO3) is a white crystalline compound that contains silver ions (Ag+) and nitrate ions (NO3-).
- When these two compounds are mixed, the sodium ions from NaCl and the nitrate ions from AgNO3 remain in solution, while the silver ions from AgNO3 and the chloride ions from NaCl combine to form a solid precipitate of silver chloride (AgCl).
- The balanced chemical equation shows that one molecule of NaCl reacts with one molecule of AgNO3 to form one molecule of AgCl and one molecule of NaNO3.

Overall, this reaction is an example of a double displacement reaction because two ionic compounds exchange ions to form two new compounds.
