Oxalic
acid is the only
possible compound in which two carboxyl
groups are joined
directly; for this reason oxalic acid is one of the
strongest
organic acids.
Unlike other carboxylic acids (
except formic acid), it is readily
oxidized; this makes it useful as a reducing
agent for
photography,
bleaching, and ink removal. Often used in
wood and
fiber bleaching.
