Para determinar si el electrodo selectivo cumple con la ecuacion de Nernst
, se construyo una curva de calibrado en el intervalo de 1,00 x [10.sup.-1] a 1,00 x [10.sup.-6] M en CMT, en funcion del potencial de celda medido para cada disolucion.
In electrochemistry, the Nernst
equation is an equation that relates the reduction potential of an electrochemical reaction (half-cell or full cell reaction) to the standard electrode potential, temperature, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation.
The cell open-circuit voltage at 750[degrees]C is around 1.1 V which is slightly lower than the Nernst
voltage of 1.110 V at the same temperature .
The Hg|HgO (1 M KOH) electrode was calibrated with respect to the reversible hydrogen electrode (RHE) according to the Nernst
equation E versus RHE = E (Hg|HgO) + 0098 + 0.0592 x pH in 1 M KOH.
Com o objetivo de calcular as constantes de entropia e as assim chamadas "constantes quimicas", Planck e Nernst
tem sido forcados a introduzir a ideia do quantum na teoria dos gases.
Comparing these values to the theoretical ones, calculated using the Nernst
equation from  to be 1.119 and 1.110 V at 700 and 750[degrees]C, respectively, indicates a well-sealed cell without any mixing of fuel and air.
As T [right arrow] 0, we notice S [right arrow] 0 indicating that Nernst
's postulate is valid.
According to Nernst
's equation the redox potential of the Ru[O.sub.2] electrode depends on the pH value:
and yet the teaching of this science rarely goes beyond redox reactions and the Nernst
Equation in General Chemistry.
