| Summary: | Composite electrode for the measurement of hydrogen ion in solution has been made from antimony, graphite, and paraffin. The dynamic range of the electrode is between pH 1.00 - 11.00 with the slopes of -51,2 ± 0.5 mV/pH and the respon time between 20 - 120 seconds. The electrode can be used for 150 measurements, as long as the surface of the electrode can be renewed. The electrode potential decreases with the slope of 1,6±0,05 rnV/°C as the temperature of the solution increases. Oxidizing and reducing agent affects the performance of the electrode, due to their ability to reduce or oxidize the active agent of the electrode. The used of this electrode for potentiometric titration and direct measurement of solution pH shows no different with glass electrode |
