4. The EMF of the electrode pair, E, in the analyzed solution with an ionic strength of 0.002 mol/l is 100 mV. Determine the activity and concentration of Cl-ions in this solution, if the following results of EMF measurements are obtained in standard KCl solutions:
СKCl, mol/l 10-4 5*10-4 10-3 5*10-3 10-2
E, mV 180 137 120 75 58
