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 : \[\overset{0}{\mathop{Cu}}\,\,+AgN{{O}_{3}}\xrightarrow[\text{oxidation}]{}\overset{+1}{\mathop{Cu}}\,N{{O}_{3}}+Ag\]You need to login to perform this action.
