The resistance of 0.2 M solution of an electrolyte is 30 ohm and conductivity are 1.2 ~S ~m ⁻¹ . What is the value of cell constant?
Options
- A0.47 ~cm ⁻¹
- B0.1 ~cm ⁻¹
- C0.36 ~cm ⁻¹
- D0.2 ~cm ⁻¹
Correct answer
C. 0.36 ~cm ⁻¹
Step-by-step solution
aligned & Conductivity ( k )= 1 R 1 ~A 1 ~A = cell constant & 1 ~A = k R =1.2 30 & =36 ~m ⁻¹ & = 36 100 ~cm ⁻¹ & 1 ~A =0.36 ~cm ⁻¹ aligned
