Question: When Cu reacts with $ AgNO_3 $ solution, the reaction takes place is
[CPMT 2004]
Options:
A) Oxidation of Cu
B) Reduction of Cu
C) Oxidation of Ag
D) Reduction of $ NO_3^{-} $
Show Answer
Answer:
Correct Answer: A
Solution:
Cu is placed above Ag in electrochemical series, hence it can replace Ag from its salts solution. Therefore the reaction occurs as follows, $ \overset{0}{\mathop{Cu}},+AgNO_3\xrightarrow{Oxidation}\overset{+1}{\mathop{Cu}},NO_3+Ag $
