A conductivity cell containing 0.001 M AgNO ₃ solution develops resistance 6530 ohm at 25^ C . Calculate the electrical conductivity of solution at same temperature if the cell constant is 0.653 ~cm ⁻¹ .
Options
- A1.3 10⁻⁴ ⁻¹ ~cm ⁻¹
- B1.5 10⁻⁴ ⁻¹ ~cm ⁻¹
- C1.7 10⁻⁴ ⁻¹ ~cm ⁻¹
- D1.0 10⁻⁴ ⁻¹ ~cm ⁻¹
Correct answer
D. 1.0 10⁻⁴ ⁻¹ ~cm ⁻¹
Step-by-step solution
array ll & Cell constant = k R & 0.653= k 6530 & k = 0.653 6530 =1 10⁻⁴ ⁻¹ ~cm ⁻¹ array
