Question

What does the given reaction indicate? $\mathrm{Cu}+2{\mathrm{AgNO}}_3\to \mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2+2\mathrm{Ag}$

Answer 1

Redox reaction:

• The reaction in which oxidation and reduction take place simultaneously is known as the Redox reaction.

Given reaction:

$$\begin{gathered} \mathrm{Cu}\left(\mathrm{s}\right)+2{\mathrm{AgNO}}_3\left(\mathrm{aq}\right)\to \mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{aq}\right)+2\mathrm{Ag}\left(\mathrm{s}\right) \\ \left(\mathrm{Copper}\right)(\mathrm{Silver}\mathrm{nitrate})(\mathrm{Copper}\mathrm{nitrate})\left(\mathrm{Silver}\right) \end{gathered}$$

• This reaction represents the redox reaction.
• Copper metal $\left(\mathrm{Cu}\right)$ is oxidized while Silver $\left(\mathrm{Ag}\right)$ gets reduced.
• Since copper displaces silver from silver nitrate solution. Thus, copper is more reactive than silver.
• Cu serves as a reducing agent while Silver nitrate $\left({\mathrm{AgNO}}_3\right)$ behaves as an oxidizing agent.
