WebMar 1, 1995 · Theoretical description of the cell constant 2.1. The cell constant in relation to the capacitance between two conductors The cell constant K [cm1] of an electrolyte con- ductivity sensor is defined as the proportionality factor between the specific resistance p [k~t cm] of the elec- trolyte and the measured resistance R,, [kf~]: Rb PK The cell ... WebWhat is the cell constant of KCl? From the value of the conductance for 0.1 M KCl, calculate the cell constant using κ KCl = 1.285 x 10 – 1 S dm – 1 (S = siemens = ohm – 1 ) at 25 °C. Using this value for the specific conductivity you can calculate all …
