Potentiometric refers to a method of measuring the voltage (or potential) of an electrochemical cell. This technique is commonly used in various fields, including chemistry and environmental science, to determine the concentration of ions in a solution. A potentiometric measurement typically involves a reference electrode and an indicator electrode, which together help assess the potential difference caused by the ions present. In practice, potentiometric measurements are often utilized in pH meters, which measure the acidity or alkalinity of a solution. The results can provide valuable information for applications in laboratories, industrial processes, and water quality monitoring.
