We have studied the conductivity of extremely anhydrous hydrogen fluoride (AHF) and obtained a minimum conductivity of at 0°C. We have recognized that water in AHF at concentrations below shows an ideal dissociation and that the limiting equivalent conductance of AHF is 436 S cm 2 mol −1 at 0°C. The ideal relationship between the conductivity and water concentration obtained in this work was extrapolated to the ultra‐micro water concentration region. The conductivity of corresponds to a water concentration of (0.033 ppm) in the above relationship; however, this conductivity is not due to the dissociation of water but to that of hydrogen fluoride. We recognized that the relationship between the conductivity and water concentration of AHF coincides completely with that of ultra‐pure water in the ultra‐micro conductivity region (10 −8 S cm −1 ).
