Answer 2

Answer:

Cell constant is the ratio of specific conductance and observed conductance.

Therefore, the option (d) is correct.

Explanation:

• The cell constant an be calculated from the distance between the electrodes (l) of the cell and their area of cross section (A).

                       $Cell\; constant =\frac{l}{A}$

• But it is difficult to measure the dimensions of the cell. Therefore we have indirect method to calculate the cell constant.
• For example, to determine the cell constant a standard solution of KCl whose conductance is known at a given temperature is taken. Then a solution of KCl of same concentration is prepared and its conductance is determined experimentally at same temperature. Both the values are substituted in the formula given below to determine the cell constant.

                    $Cell\; constant =\frac{Specific \; conductance}{Observed\; conductance}$

Hence we can use the ratio of specific and observed conductance to determine the cell constant.
