konduktometria

Konduktometria is a scientific technique used to measure the electrical conductivity of a solution. This method involves passing an electric current through a cell containing the solution, and measuring the resulting voltage drop across the cell.

The principle of konduktometria is based on the fact that ions in a solution can conduct electricity. By applying an electric field across the solution, ions are attracted to the electrodes and move through the solution, allowing the current to flow. The conductivity of the solution is measured by the resistance it presents to the flow of current.

Konduktometria can be used to determine the concentration of ions in a solution. As the concentration of ions increases, the conductivity of the solution also increases. By measuring the conductivity of the solution at different concentrations, a calibration curve can be created to relate conductivity to concentration.

There are several types of konduktometria cells, including cell cells and cells with embedded electrodes. Cell cells are simple electrodes immersed in the solution, while cells with embedded electrodes have a mutually supporting tube filled with conductive material to support the electrodes. This design allows for higher sensitivity measurements.

In addition to determining ion concentration, konduktometria is also used to control the concentration of solutions in processes such as electrolytic purification. The technique is widely used in analytical chemistry and other fields where ionconcentration is an important variable.

Modern konduktometer instruments are computer controlled and automatically analyze the conductivity of the solution. The software included with the instruments also allows the user to create calibration curves and perform data analysis.
