A conductivity cell has been calibrated with 0.01 M 1 : 1 electrolyte solution (specific conductance, k = 1.25 × 1 0 − 3 S cm − 1 ) in the cell and the measured resistance was 800Ω at 2 5 ∘ C . The cell constant will be

TestHub · Accepted Answer

Given, K = 1.25 × 1 0 − 3 S cm − 1 ρ = x 1 ​ = 1.25 × 1 0 − 3 1 ​ S − 1 cm From R 800 ​ = ρ A 1 ​ = 1.25 × 1 0 − 3 1 ​ × A 1 ​ ​ (where, A 1 ​ = cell constant) ∴ A 1 ​ ​ = 800 × 1.25 × 1 0 − 3 = 1 cm − 1 ​
