Which type of reaction is NaCl + AgNO3 → NaNO3 + AgCl?

Question

synthesis
decomposition
oxidation
replacement

Answer 1

The reaction $\text{NaCl}+{\text{AgNO}}_3\to {\text{NaNO}}_3+\text{AgCl}$ is a replacement reaction (also known as a double displacement reaction). In this type of reaction, the cations and anions of the reactants exchange partners to form new products. Here, sodium (Na) and silver (Ag) exchange their anions (chloride and nitrate) to form sodium nitrate and silver chloride.
