介 電 常數

中,介電常數是溶劑的一個重要性質,它表徵溶劑對溶質分子溶劑化以及隔開離子的能力。介電常數大的溶劑,有較大隔開離子的能力,同時也具有較強的溶劑化能力。介電常數用ε表示,一些常用溶劑 . following table gives some typical values The relative low frequency permittivity of ice is ~96 at −108 °C, falling to 315 at high frequency, which is independent of temperature [21] It remains in the range 312–319 for
