摘要：

Stability quotients for the hydrogen-fluoride and aluminum-fluoride systems in NH4NO3 were determined from measurements of free fluoride ion concentration by the lanthanum fluoride membrane electrode. Stability quotients at 0·5, 0·3, 0·1, and 0·01 M ionic strength were extrapolated to infinite dilution through the Debye-Hückel equation to obtain thermodynamic stability constants at 25°C for HF, HF2-, AlF2+, AlF2+, AlF3, and AlF4-. © 1969.
