Determination of cell constant
WebJan 13, 2010 · From Eq.(5) we can determine the cell constant C: C= l/A (5) The cell constant, C, with units m-1, can be also determined by measuring the resistance of a cell filled with a solution of known conductivity, which is invariably KCl (usually 0.0200 M). Once the cell constant Chas been determined, conductivity of any solution can be calculated … WebWhat is Cell Constant? Solution The resistance of a conductor ( R) is directly proportional to its length ( l) and cross-sectional area ( A) as given by the equation R = ρ l A where ρ …
