kalomelelektrodit
Kalomelelektrodit, or calomel electrodes, are a type of reference electrode widely used in electrochemistry. They consist of mercury in contact with mercurous chloride (calomel), which is itself in contact with a solution containing chloride ions. This specific arrangement creates a stable and reproducible potential, making the calomel electrode a reliable standard against which the potential of other electrodes can be measured. The electrochemical reaction involved is: Hg(l) + Cl-(aq) <=> 1/2 Hg2Cl2(s) + e-.
The calomel electrode is typically constructed with a glass tube containing mercury at the bottom. Above the
The primary advantage of the calomel electrode is its stability and ease of construction. It is less
