A conductivity cell shows resistance of 600 ohm . If conductivity of 0.01 M KCl is 0.0015 ⁻¹ ~cm ⁻¹ , what is cell constant?
Options
- A0.60 ~cm ⁻¹
- B0.45 ~cm ⁻¹
- C0.90 ~cm ⁻¹
- D75 ~cm ⁻¹
Correct answer
C. 0.90 ~cm ⁻¹
Step-by-step solution
aligned & R =600 , k _ KCl =0.0015 ⁻ cm ⁻¹, c =0.01 M Cell constant = & k _ KCl R _ solution =0.0015 ⁻¹ ~cm ⁻¹ 600 =0.90 ~cm ⁻¹ aligned
