Question

Name the type of chemical reaction that occurs between a solution of sodium chloride and a solution of silver nitrate.

Answer 1

• A chemical reaction in which two substances which is in liquid form produces a precipitate that is semi-solid by exchange of radicals is called a precipitation reaction.
• In this reaction, sodium$\left(\mathrm{Na}\right)$ being highly reactive displaces silver$\left(\mathrm{Ag}\right)$ which is less reactive and forms sodium nitrate$\left({\mathrm{NaNO}}_3\right)$. Silver chloride$\left(\mathrm{AgCl}\right)$ is the precipitate formed.

$$\begin{gathered} {\mathrm{AgNO}}_3\left(\mathrm{s}\right)+\mathrm{NaCl}\left(\mathrm{s}\right)\to \mathrm{AgCl}\left(\mathrm{s}\right)+{\mathrm{NaNO}}_3\left(\mathrm{s}\right) \\ \mathrm{Silver}\mathrm{nitrate}\mathrm{Sodium}\mathrm{chloride}\mathrm{Silver}\mathrm{chloride}\mathrm{Sodium}\mathrm{nitrate} \end{gathered}$$
