Redox Reactions And Electrochemistry Ques 598
Question: The EMF of the cell $ Tl/T{l^{+}}(0.001M)||C{u^{2+}}(0.01M)/Cu,is,0.83. $ The cell EMF can be increased by
Options:
A) Increasing the concentration of $ T{l^{+}} $ ions.
B) Increasing the concentration of $ C{u^{2+}} $ ions.
C) Increasing the concentration of $ T{l^{+}} $ and $ C{u^{2+}} $ ions.
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The oxidation potential $ \propto \frac{1}{Concentrationofions} $ and reduction potential $ \propto $ concentration of ions. The cell voltage can be increased by decreasing the concentration of ions around anode or by increasing the concentration of ions around cathode
