Proton-fluoride equilibria in concentrated sodium perchlorate media

  • G. T. Hefter
Article

Abstract

The stability constant of HF has been measured at 25°C in concentrated sodium perchlorate media at ionic strengths ranging from 2 to 8M. Results were obtained by fluoride ion-selective electrode potentiometry. Agreement with literature values is excellent where comparison is possible.

Key words
