Understanding Reference Electrodes: Hg/HgO and Their Importance
In electrochemical systems, reference electrodes play a crucial role by providing a stable and well-defined potential against which other electrode potentials can be measured. They serve as essential components in electrochemical cells, ensuring accurate and consistent readings in various research and industrial applications. Among the widely used reference electrodes is the Hg/HgO (Mercury/Mercury Oxide) reference electrode, known for its stability in alkaline environments. The Hg/HgO reference electrode is particularly useful in situations where a reference point is needed in high pH conditions. It consists of mercury in equilibrium with mercury oxide, immersed in an alkaline solution. The electrode offers reliable and reproducible results, especially in studies and industries related to battery research, corrosion studies, and other electrochemical experiments requiring consistent reference potential in alkaline media. Compared to other reference electrodes, the Hg/HgO e...
