konduktometrie

Konduktometrie, also known as conductivity measurement, is an analytical chemistry technique used to determine the electrical conductivity of a solution. This property is directly related to the concentration of dissolved ions present in the solution. Pure water has very low conductivity, but the presence of dissolved salts, acids, or bases increases its conductivity due to the movement of charged ions.

The principle behind konduktometrie relies on Ohm's law, which states that the current flowing through a conductor is proportional to the voltage applied across it and inversely proportional to its resistance. In a konduktometric measurement, two electrodes are immersed in the solution, and a known voltage is applied. The resulting current is then measured. The conductivity is then calculated from this current, voltage, and the cell constant of the conductivity cell.

Konduktometrie is a versatile technique with numerous applications. It is commonly used to monitor water quality, for example, in checking the purity of deionized water or assessing the salinity of natural water bodies. In industrial processes, it can be used to control the concentration of solutions in electroplating, chemical manufacturing, and food and beverage production. It is also employed in environmental monitoring to detect pollutants in water. The technique is relatively simple, rapid, and can be performed in situ, making it a valuable tool for various analytical needs.
