Description / Abstract: Describes a method based on the potentiometric titration of the chloride ions with standard volumetric silver nitrate solution in an acid medium and in the presence of acetone, using a silver electrode or a chloride or silver ion-selective electrode (measuring electrode) and a calomel or a mercury(I) sulphate electrode (reference electrode). Is a applicable to test solutions having chloride concentrations, expressed in milligrams per litre, of between 1 and 1500.
