Web14. apr 2024 · The Nernst equation E=E0-pH*2.3RT/F (where E: measured potential, E0, R and F are both constants), and only the temperature is unknown in the slope of the equation 2.3RT/F. When the temperature is different, the slope of pH is different, so the temperature compensation of pH usually refers to compensating the slope of the electrode ... WebProvette contenenti soluzioni di pH 1-10 colorate con un indicatore universale.. Il pH (pronunciato come sigla "pi acca"), che denota storicamente il potential of hydrogen ("potenziale di idrogeno"), è una grandezza fisica che indica l'acidità (e quindi la basicità) in soluzioni gassose e liquide..
