reference electrode
[/ˈrɛfərəns ɪˈlɛktrəʊd/]
nounpl: reference electrodes
eletrodo de referência
1. An electrode with a stable and well-known electrode potential, used in electrochemical measurements to measure the potential of other electrodes
The silver-silver chloride electrode serves as a reference electrode in many electrochemical experiments.
O eletrodo de prata-cloreto de prata funciona como eletrodo de referência em muitos experimentos eletroquímicos.
2. A half-cell with a constant potential that allows measurement of electrode potential differences in electrochemical cells
In pH measurements, a reference electrode maintains a constant potential against which other potentials are measured.
Nas medições de pH, um eletrodo de referência mantém um potencial constante contra o qual outros potenciais são medidos.
Reference electrodes are fundamental in electrochemistry and are taught extensively in chemistry and engineering programs throughout Brazil and Portuguese-speaking countries. The term is standardized in scientific literature and is crucial in analytical chemistry laboratories, pharmaceutical analysis, and corrosion studies.
