The test solution (NaCl) were prepared at different concentrations, standard silver nitrate solutions were also prepared at different concentrations. Titration of these (NaCl) solutions against different concentrations was carried out using (5%) potassium chromate as indicator, the recorded results showed high validity. Different concentrations of indicator were also prepared and titrations were carried out using these different concentrations to find the most suitable indicator concentrations for Mohr‘s titration. It was found that 5% is the most suitable indicator. By using the conductmetric titration, the obtained data showed similar results between titrimetric and conductimetric method. l IVControl ParametersChemistryControl ParametersThesis
