Redox Reactions And Electrochemistry Ques 546
Question: Which of the following reaction is a redox reaction [MP PMT 2003]
Options:
A) $ P_2O_5+2H_2O\to H_4P_2O_7 $
B) $ 2AgNO_3+BaCl_2\to 2AgCl+Ba{{(NO_3)}_2} $
C) $ BaCl_2+H_2SO_4\to BaSO_4+2HCl $
D) $ Cu+2AgNO_3\to 2Ag+Cu{{(NO_3)}_2} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \overset{,o}{\mathop{Cu}},+\overset{+1,}{\mathop{2AgNO_3}},\to \overset{+2,}{\mathop{Cu{{(NO_3)}_2}}},+\overset{o}{\mathop{2Ag}}, $ . This is a redox reaction.
