Abstract
The ionization constant, , for the reaction HF⇄H + F was calculated on the basis of potentiometric measurements in the cell Ag; AgCl, Cl, F∥LaF∥NaF, HCl, HO∣KCl(Satd.), HgCl; H at 25 °C. A least squares procedure was applied to the experimental data yielding a best estimate for of 5.85 × 10 with a standard error of 0.03 × 10
摘要
对于反应HF⇄H⁺ + F⁻的电离常数，是在25℃下通过电池Ag；AgCl，Cl⁻，F⁻∥LaF₃∥NaF，HCl，H₂O∣KCl（饱和），Hg₂Cl₂；Hg的电位测量来计算的。对实验数据应用了最小二乘法，得出电离常数的最佳估计值为5.85×10⁻⁴，标准误差为0.03×10⁻⁴ 。
