The resistance of a conductivity cell containing 0.001 M KC1 solution at 300 ~K is 150 . What is the cell constant if conductivity of KCl solution is 1.5 10⁻ ⁻¹ ~cm ⁻¹
Options
- A0.112 ~cm ⁻¹
- B0.225 ~cm ⁻¹
- C0.337 ~cm ⁻¹
- D0.450 ~cm ⁻¹
Correct answer
B. 0.225 ~cm ⁻¹
Step-by-step solution
We know K = 1 R = ( L A ) aligned & 1.5 10⁻³= 1 150 ( L A ) & L A =0.225 ~cm ⁻¹ aligned
