Redox Reactions And Electrochemistry Ques 189
Question: Which will increase the voltage of the cell $ S{n _{(s)}}+2A{g^{+}} _{(aq)}\to S{n^{2+}} _{(aq)}+2A{g _{(s)}} $ [DPMT 2001]
Options:
A) Increase in the concentration of $ A{g^{+}} $ ions
B) Increase in the concentration of $ S{n^{2+}} $ ions
C) Increase in size of the silver rod
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
$ {E_{cell}}=E_{cell}^{o}+\frac{0.059}{2}\log \frac{(A{g^{+}})}{(S{n^{2+}})} $ .
