The temperature-dependent form of the extended Debye-Huckel equation is where γ is the activity coefficient, ε is the dielectric constant of water (a unitless quantity), T is the temperature (in units of K), z is the charge of the ion, μ is the ionic strength (in units of mol/L), and α is the ion size parameter (in units of pm). The temperature-dependence of the dielectric constant is given by the equation where the temperature is in units of Kelvin. What...
