The resistance of 0.01 ~m KCl solution at 298 ~K is 1500 . If the conductivity of 0.01 ~m KCl solution at 298 ~K is 0.1466 10⁻³ ~S ~cm ⁻¹ . The cell constant of the conductivity cell in cm ⁻¹ is
Options
- A0.219
- B0.291
- C0.301
- D0.194
Correct answer
A. 0.219
Step-by-step solution
Given, concentration of KCl solution =0.01 ~m Resistance (R) of KCl solution =1500 Conductivity (K) of 0.01 ~m KCl solution at 298 ~K aligned &=0.1466 10⁻³ ~S ~cm ⁻¹ & Cell constant (G^ * )= R &=0.1466 10⁻³ 1500 &=0.219 aligned
