comparative electrode
[kəm-ˈper-ə-tiv i-ˈlek-ˌtrōd]
nounpl: comparative electrodes
eletrodo comparativo
1. A reference electrode used in electrochemistry to measure the potential difference between itself and a test electrode in a solution
The comparative electrode remained stable throughout the experiment, allowing accurate measurement of the sample electrode's potential.
O eletrodo comparativo permaneceu estável durante todo o experimento, permitindo medição precisa do potencial do eletrodo da amostra.
2. An electrode that serves as a standard or baseline for comparison in electrochemical measurements
In this titration setup, the comparative electrode was calibrated before each measurement to ensure reliability.
Nessa configuração de titulação, o eletrodo comparativo foi calibrado antes de cada medição para garantir confiabilidade.
This is primarily technical/scientific terminology used in chemistry, electrochemistry, and analytical laboratories in both Brazil and the USA. The term is standardized in scientific nomenclature and academic publications across Portuguese and English-speaking countries. In Brazil, 'eletrodo comparativo' and 'eletrodo de referência' are often used interchangeably in scientific contexts.
