potensiametrisesti

Potensiametrisesti refers to a method used in analytical chemistry to measure the electric potential of a solution. This technique is a cornerstone of potentiometry, a branch of electrochemistry. In essence, potentiometry involves using an electrochemical cell where the potential difference between two electrodes is measured. One electrode is typically a reference electrode with a stable and known potential, while the other is an indicator electrode that responds to the concentration of a specific ion in the solution.

The measured potential is directly related to the activity (or concentration, under certain approximations) of the ion being analyzed, as described by the Nernst equation. This relationship allows for the quantitative determination of various species, including ions like hydrogen (pH measurement), fluoride, chloride, and many others. Potensiametrisesti measurements are widely employed in diverse fields such as environmental monitoring, industrial process control, clinical diagnostics, and food analysis due to their sensitivity, accuracy, and often non-destructive nature. The instrumentation used for these measurements is called a potentiometer or a pH meter, which displays the measured potential.
