A conductivity cell dipped in 0.05 M KCl has resistance 600 ohm . If conductivity is 0.0012 ohm ⁻¹ ~cm ⁻¹ . What is the value of cell constant?
Options
- A0.50 ~cm ⁻¹
- B0.72 ~cm ⁻¹
- C1.5 ~cm ⁻¹
- D2.0 ~cm ⁻¹
Correct answer
B. 0.72 ~cm ⁻¹
Step-by-step solution
aligned & Conductivity ( k )= Cell constant R & Cell constant = k R = & 0.0012 ohm ⁻¹ ~cm ⁻¹ 600 ohm =0.72 ~cm ⁻¹ aligned
