JEE Main & Advanced Chemistry Electrochemistry / विद्युत् रसायन Question Bank Cell constant and Electrochemical cells

  • question_answer
    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]

    A)                 \[0.142\,c{{m}^{-1}}\]   

    B)                 \[0.66\,c{{m}^{-1}}\]

    C)                 \[0.918\,c{{m}^{-1}}\]   

    D)                 \[1.12\,c{{m}^{-1}}\]

    Correct Answer: B

    Solution :

               \[K=\frac{1}{R}\times \]Cell constant                                 Cell constant \[=K\times R\]; \[0.012\times 55=0.66\ c{{m}^{-1}}\].
