Question

The distance between electrodes of a conductivity cell is 0.98 cm and area of cross section is 1.96 cm^2. What is the cell constant?

Options

• 2 cm⁻¹

• 1.5 cm⁻¹

• 0.5 cm⁻¹

• 1 cm⁻¹

Answer 1

0.5 cm⁻¹

Explanation:

Cell constant, b = `"l"/"a" = (0.98  "cm")/(1.96  "cm"^2)` = 0.5 cm⁻¹
