A) Oxidation of Cu
B) Reduction of Cu
C) Oxidation of Ag
D) Reduction of\[N{{O}_{3}}\]
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: \[\overset{0}{\mathop{C}}\,u+AgN{{O}_{3}}\xrightarrow[oxidation]{{}}\overset{+1}{\mathop{C}}\,uN{{O}_{3}}+Ag\]
