. In a conductivity cell the two platinum electrodes

each of area 10 sq cm, are fixed 1.5 cm apart. The cell contained 0.05 N solution of a salt. If the two electrodes are just half dipped into the solution which has a resistance of 50 ohms, find equivalent conductance of the salt solution.

A. 120 mho cm2. Eq–1                  

B. 240 mho cm2. eq–1

C. 80 mho cm2. eq–1                    

D. 889 mho cm2. eq–1

Best Answer

Ans: A

Sol: Since the electrodes of the cell are just half dipped, the effective area will be 5 sq. cm.
