2. A quantitative electrochemical method based on Faraday's law, where the amount of substance is determined by the total amount of electricity consumed
The laboratory employed coulometry to verify the exact concentration of the titrant.
O laboratório utilizou coulometria para verificar a concentração exata do titulante.
Coulometry is a specialized scientific term used exclusively in academic and professional chemistry laboratories. Both Brazilian Portuguese and European Portuguese use 'coulometria' without significant regional variation.
