comparison electrode
[kəmˈpærɪsən ɪˈlɛkˌtroʊd]
nounpl: comparison electrodes
eletrodo de referência
1. An electrode of known potential used as a reference point in electrochemical measurements to determine the potential of another electrode or solution
The comparison electrode remained stable throughout the experiment to ensure accurate voltage readings.
O eletrodo de referência permaneceu estável durante todo o experimento para garantir leituras de voltagem precisas.
2. In electrochemistry, a half-cell with a constant and well-defined electrode potential against which other electrodes are measured
Common comparison electrodes include the saturated calomel electrode and the silver/silver chloride electrode.
Eletrodos de referência comuns incluem o eletrodo de calomelano saturado e o eletrodo de prata/cloreto de prata.
This is a technical term primarily used in scientific and academic contexts in both Brazil and the United States. It is essential terminology in electrochemistry courses and laboratory work. There are no significant regional variations in usage, though Brazilian Portuguese may prefer 'eletrodo de referência' while the literal translation 'eletrodo de comparação' is occasionally used in technical documentation.
