reduction potential
[rɪˈdʌkʃən pəˈtɛnʃəl]
nounpl: reduction potentials
potencial de redução
1. A measure of the tendency of a chemical species to acquire electrons and be reduced, expressed in volts relative to a standard reference electrode (typically the standard hydrogen electrode)
The reduction potential of silver is +0.80 V, indicating its strong tendency to be reduced.
O potencial de redução da prata é +0,80 V, indicando sua forte tendência de ser reduzida.
2. In electrochemistry, a quantitative measure of the oxidation-reduction (redox) activity of a chemical species in solution
By comparing reduction potentials, we can predict which species will be oxidized and which will be reduced in a redox reaction.
Comparando potenciais de redução, podemos prever quais espécies serão oxidadas e quais serão reduzidas em uma reação redox.
3. The standard cell potential (E°) for a half-reaction under standard conditions
The reduction potential is used to calculate the overall cell potential of an electrochemical cell.
O potencial de redução é usado para calcular o potencial de célula geral de uma célula eletroquímica.
This is a technical term primarily used in scientific and academic contexts within both the USA and Brazil. It is fundamental to the study of electrochemistry and biochemistry, particularly important in understanding battery performance, corrosion, and biological electron transfer processes. The term is standardized internationally in scientific literature and is not subject to regional variations in meaning.
