I-Objective :- - To obtain the electrical conductivity of KCl and acetic acid solutions. - Finding out the limiting conductivity for the two solutions. - To find the dissociation constant of acetic acid. II-Theory :- Some substances that dissociate into ions by some suitable solvents can conduct electricity. Therefore, the conductance of these solutions depends on the degree of dissociation and the concentration of ions. The electrical conductivity, k , is the conductance of a cube of a solution which is contained between two parallel electrodes 1 cm square and 1 cm apart, and it can be found by: k G l A = (1) Where, G = the conductance, S l = the length of material, cm A = the cross-sectional area, cm 2 K = the electrical conductivity, S cm The molar conductivity, Λ , can be defined as, Λ = k c / (2) Where, c = the concentration, mol/ cm 3 Λ = The molar conductivity, S cm
