Q. When Cu reacts with ${AgNO}_{3}$ solution, the reaction takes place is
A) Oxidation of Cu
B) Reduction of Cu
C) Oxidation of Ag
D) Reduction of ${NO}_{3}^{-}$
Explanation
(a)
Cu is placed above Ag in electrochemical series, hence it can replace Ag from its salts solution. Therefore, the reaction occur as follows
O +1
$Cu\ + \ {AgNO}_{3}\ \overset{\ \ \ Oxidation\ \ \ \ \ }{\rightarrow}\ \ {CuNO}_{3}\ + \ Ag$
