NCERT · Class 12 · Chemistry · ElectrochemistryWhat is the cell constant of a conductivity cell having distance between electrodes $l$ and cross-sectional area $A$?
Step-by-Step Solution
The correct option is $l/A$. The cell constant ($G^$) is defined as the ratio of the distance between the electrodes ($l$) to the cross-sectional area of the electrodes ($A$). It is expressed as $G^ = l/A$. Its unit is cm⁻¹ or m⁻¹.
