A) oxidation of\[Cu\]
B) reduction of\[Cu\]
C) oxidation of\[Ag\]
D) reduction of\[NO_{3}^{-}\]
Correct Answer: A
Solution :
\[Cu\] is placed above \[Ag\] in electrochemical series, hence it can replace Ag from its salts solution. Therefore the reaction occur as follows: \[\overset{0}{\mathop{Cu}}\,+AgN{{O}_{3}}\xrightarrow[oxidation]{}\overset{-1}{\mathop{C}}\,uN{{O}_{3}}+Ag\]
