Abstract
A study of the H+/F− system by fluoride ion-selective electrode potentiometry over a range of ionic strengths in LiClO 4 gives protolysis constants which differ markedly from those obtained in other media such as NaClO 4 . This is shown to be consistent with the competitive complexation of the fluoride ion by the lithium ion. An examination of literature data indicates that lithium ion complexation is a general phenomenon and supports the conclusion that LiClO 4 is not preferable to NaClO 4 as a swamping electrolyte for the study of protolytic equilibria as has previously been thought.
