PREPARATION AND STUDY OF ACETATE ION SENSITIVE ELECTRODE

Various methods such as silicon grease, pellet, PVC and coated wire were employed for preparation of acetate sensitive electrode. Reproducibility of electrode potential, response time and their stability were investigated. The potential of electrode has been studied with different concentrations of acetate ion. These electrodes were used for direct potentiometric determination of acetate ion in food preservatives (vinegar sample), water and water-alcohol mixture solvents. Suitable empirical equations have been developed for reliability of data. Electrodes were also used as an end point detector in potentiometric titration.
