Potenciometricky

Potenciometricky refers to methods and techniques that utilize potentiometry. Potentiometry is an electrochemical technique used to measure the electric potential difference between two electrodes in a solution. This potential difference is directly related to the concentration of specific ions in the solution.

The core principle behind potentiometry is the Nernst equation, which relates the electrode potential to the activity (and by extension, concentration) of ions. A common setup involves a reference electrode, which has a stable and known potential, and a working electrode, whose potential changes with ion concentration. The measured potential difference allows for the quantitative determination of the analyte.

Applications of potentiometry are widespread. It is used in analytical chemistry for determining ion concentrations in various matrices, including water quality analysis, food testing, and clinical diagnostics. Ion-selective electrodes (ISEs) are a key component in many potentiometric measurements, designed to respond specifically to a particular ion.

Potentiometric titration is another important application. In this method, the potential is monitored as a titrant is added to the analyte solution. The equivalence point of the titration is identified by a significant change in the measured potential, allowing for the determination of the analyte's concentration. This technique is useful for a variety of acid-base, precipitation, and redox titrations. Potenciometricky measurements offer a non-destructive and often rapid method for chemical analysis.
