Redox Reactions And Electrochemistry Question 188
Question: Saturated solution of $ KNO_3 $ is used to make -salt-bridge- because [IIT Screening 2002]
Options:
A) Velocity of $ {K^{+}} $ is greater than that of $ NO_3^{-} $
B) Velocity of $ NO_3^{-} $ is greater than that of $ {K^{+}} $
C) Velocities of both $ {K^{+}} $ and $ NO_3^{-} $ are nearly the same
D) $ KNO_3 $ is highly soluble in water
Show Answer
Answer:
Correct Answer: C
Solution:
Velocities of both $ {K^{+}} $ and $ NO_3^{-} $ are nearly the same in $ KNO_3 $ so it is used to make salt-bridge.
