    Control Parameters of M0hr‘s Titrtion
    (ALNEELAIN UNIVERSITY, 2014-11) Eman Mohammed Babikir Elgzoly
    Abstract The aim of this research is to test validity and reproducibility of mohr‘s titration by using different parameters. 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 IV
