Static self potential

Input(s)

tClt_{C l}: Chlorine Anion Transference Number (dimensionless)

R\mathrm{R}: Gas Constant (J/(\mathrm{J} / degree C)\mathrm{C})

TaT_{a}: Absolute Temperature (degree K)

F: Faraday Constant (96485.336) (s A/mol)

awa_{w}: Activity of NaCl\mathrm{NaCl} (dimensionless)

amfa_{m f}: Activity of Dilute Solution (dimensionless)

Output(s)

K\mathrm{K}: Equilibrium Constant (mV)(\mathrm{mV})

EsspE_{s s p}: Static Self Potential (V)

Formula(s)

K=4.606tCl(RTaF)Essp=Klog(awamf)\begin{gathered} K=4.606 * t_{C l} *\left(R * \frac{T_{a}}{F}\right) \\ E_{s s p}=-K * \log \left(\frac{a_{w}}{a_{m f}}\right) \end{gathered}
