When $\mathrm{Cu}$ reacts with $\mathrm{AgNO}_{3}$ solution, the reaction takes place is

When $\mathrm{Cu}$ reacts with $\mathrm{AgNO}_{3}$ solution, the reaction takes place is
  1. oxidation of $\mathrm{Cu}$
  2. reduction of $\mathrm{Cu}$
  3. oxidation of $\mathrm{Ag}^{+}$
  4. reduction of $\mathrm{NO}_{3}^{-}$

Solution

$\mathrm{Cu}^{0}+2 \mathrm{AgNO}_{3} ightarrow \mathrm{Cu}^{2+}\left(\mathrm{NO}_{3}ight)_{2}+2 \mathrm{Ag}$
It is oxidation of copper $\left(\mathrm{Cu}^{0} ightarrow \mathrm{Cu}^{2+}ight)$
