A study of the H+/F− system by fluoride ion-selective electrode potentiometry over a range of ionic strengths in LiClO4 gives protolysis constants which differ markedly from those obtained in other media such as NaClO4. 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 LiClO4 is not preferable to NaClO4 as a swamping electrolyte for the study of protolytic equilibria as has previously been thought.
