Poorana sundari 1 Department of Chemistry, Avinashilingam University for women, Coimbatore - 641043 (INDIA) <p style="text-align: justify;">A heterogenous precipitate has been used as ion carriers for the preparation of chloride selective membrane sensor. The electrodes give near-Nernsitian response in the linear concentration range of 1M to 1x10^-6 M with detection limits of the orders of 10^-6 M. The stable potentiometric signals are obtained with in a short time period of 5seconds. The effect of pH and the effect of medium, have been studied, found to give a better responses Selectivity coefficient values (log&nbsp;) evaluated using fixed interference method. The sensors have also been used as an indicator electrode in potentiometric acid base titration</p> https://journalofchemistry.org/paper/677/ potentiometric indicator electrode
