Whether a compound containing such an X-O-H group is an acid or a
base depends on which bond is stronger, X-O or O-H, as illustrated
If X represents an atom of low electronegativity such as lithium,
then oxygen pulls the electrons in the X-O bond toward itself, and
in aqueous solutions the substance dissociates in the following way:
Because hydroxide ions are produced, the substance is a base. Lithium
hydroxide, LiOH, is an example.
