Question

The specific conductance of 0.1 N KCl solution at 23°C is 0.012 Ohm^-1 cm^-1 . The resistance of the cell containing the solution at the same temperature was found to be 55 Ohm. The cell constant will be …………

(a) 0.142 cm^-1 

(b) 0.66 cm^-1

(c) 0.9 18 cm^-1 

(d) 1.12 cm^-1

Answer 1

(c) 0.9 18 cm^-1 

k x \(\frac{1}{R}\) x cell constant

Cell constant = k x R 

= 0.012 x 55 

= 0.66 cm^-1
