General Description:Oxalic Acid (also called Ethanedioic
Acid) is a colourless, crystalline, toxic organic compound belonging
to the family of dicarboxylic acids; melting at 187 C; soluble in water,
alcohol, and ether. 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 acids in organic compounds. Unlike other carboxylic
acids, oxalic acid readily oxidize and combine with calcium, iron, sodium,
magnesium, or potassium to form less soluble salts called oxalates.
Oxalic acid and oxalates are useful as reducing agents for photography,
bleaching, and rust removal. They are widely used as a purifying agent
in pharmaceutical industry, precipitating agent in rare-earth metal
processing, bleaching agent in textile and wood industry, rust-remover
for metal treatment, grinding agent, waste water treatment. Acid rinse
in laundries and removing scale from automobile radiators.

Uses of Oxalic acid.
- In household chemical products such as Bar Keeper's Friend, some bleaches, and rustproofing treatments.
- In wood restorers
where the acid dissolves away a layer of dry surface wood to expose
fresh material underneath.
- As an additive
to automotive wheel cleaners.
- As a mordant in dyeing processes.
- Used in platinotype, the early photographic Platinum/Palladium
printing process.
- Vaporized oxalic acid, or a 6% solution of oxalic acid in sugar
syrup, is used by some beekeepers as an insecticide against the
parasitic Varroa mite.
- As a rust remover
in such applications as automotive shops and for the restoration of
antiques.
- As a recommended
surface pretreatment for stainless steels (surface etch) before application
of solid metal or polymer self-lubricating coatings.
- For polishing
stones and marble.
- Used in the acid
treatment for destroying warts
