Redox Reactions And Electrochemistry Ques 16
Question: The specific conductance of a 0.1 N KCl solution at $ 23^{o}C $ is $ 0.012,oh{m^{-1,}}c{m^{-1}} $ . The resistance of cell containing the solution at the same temperature was found to be 55 ohm. The cell constant will be [CBSE PMT 1999, 2000; KCET 2001]
Options:
A) $ 0.142,c{m^{-1}} $
B) $ 0.66,c{m^{-1}} $
C) $ 0.918,c{m^{-1}} $
D) $ 1.12,c{m^{-1}} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ K=\frac{1}{R}\times $ Cell constant Cell constant $ =K\times R $ ; $ 0.012\times 55=0.66\ c{m^{-1}} $ .
