potensiometrik

Potensiometrik refers to a method of chemical analysis that measures the electrical potential of a solution. This technique relies on the principle that the potential difference between two electrodes immersed in an electrolyte solution is related to the concentration of specific ions in that solution. A common setup involves a working electrode and a reference electrode. The working electrode is designed to be responsive to the analyte of interest, while the reference electrode maintains a constant potential. By measuring the voltage difference between these two electrodes, the concentration of the analyte can be determined.

Potentiometric methods are widely used in various fields, including environmental monitoring, industrial process control, and clinical diagnostics. For example, pH meters, which measure the hydrogen ion concentration, are a familiar application of potentiometry. Other applications include determining the concentration of halide ions, heavy metals, and dissolved gases. The advantages of potentiometry include its relative simplicity, low cost, and the ability to perform non-destructive measurements. However, accuracy can be affected by factors such as temperature, the presence of interfering ions, and the calibration of the electrodes.
