Question

The specific conductivity of  N/10KCl solution at 20°C is 0.0212 ohm^-1 cm^-1 and the resistance of cell containing this solution at 20°C is 55 ohm. The cell constant is

(a) 2.173 cm^-1

(b) 1.166 cm^-1

(c) 4.616 cm^-1

(d) 3.324 cm^-1

Answer 1

Correct option (b) 1.166 cm^-1

Explanation:

We know that,

Specific conductance: Cell constant x Conductance

= Cell constant: Resistance x specific conductance

= 0.0212 x 55 = 1.166 cm^-1
