Potentiometriä

Potentiometriä is a Finnish term that translates to "potentiometry" in English. Potentiometry is an electrochemical technique used to measure the electrical potential of a solution. This measurement is made without drawing any significant current from the solution, hence the name "potentiometry," which refers to measuring potential.

In potentiometry, a specific ion-selective electrode is immersed in a solution, and its potential is measured relative to a stable reference electrode. The potential difference between these two electrodes is directly related to the concentration of the ion being measured in the solution. This relationship is typically described by the Nernst equation.

Potentiometry is a versatile analytical method widely used in various fields. It is employed for determining the concentration of specific ions, such as hydrogen ions (pH measurement), halides, and metal ions, in water quality analysis, environmental monitoring, and industrial process control. It is also utilized in clinical diagnostics for measuring electrolyte concentrations in biological fluids and in pharmaceutical analysis for quality control. The simplicity, speed, and accuracy of potentiometric methods make them a valuable tool for quantitative analysis.
