A detailed experimental investigation of the association (acidity) constant of hydrofluoric acid has been made at 25°C in sodium perchlorate media at ionic strengths between 0.01 and 0.5M. Results were obtained by potentiometry using a fluoride ion-selective electrode in conjunction with three types of reference electrode, all involving cells with liquid junction. After careful consideration of possible errors in the present results and a critical study of the literature, a zero ionic strength pK a o (HF) value of 3.18±0.02 is recommended until existing contradictions can be resolved.
