- Oxalic acid is the
chemical compound with the formula H2C2O4. This dicarboxylic acid is
better described with the formula HOOCCOOH.
- Oxalic acid is a
relatively strong organic acid, being about 10,000 times stronger than
acetic acid.
- The di-anion,
known as oxalate, is also a reducing agent as well as a ligand in
coordination chemistry.
- Oxalic acid can be
prepared in the laboratory by oxidizing sucrose using nitric acid in the
presence of a small amount of vanadium pentoxide as a catalyst.
- On a large scale,
sodium oxalate is manufactured by absorbing carbon monoxide under
pressure in hot sodium hydroxide.
- Oxalic acid is obtained
as the dihydrate. This solid can be dehydrated with heat or by
azeotropic distillation.
- Anhydrous oxalic acid
exists as two polymorphs; in one the hydrogen-bonding results in a
chain-like structure whereas the hydrogen bonding pattern in the other
form defines a sheet-like structure.
- Oxalic acid can be
prepared via oxidation of either Glycolic acid or Ethylene glycol. In
one synthetic path, Nitric acid is used to oxidize either of the two in
the presence of oxygen.
- 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.
- Precipitation can be
caused by calcium oxalate if a high concentration of oxalic acid is
present because calcium ions are released in the brewing
process.
This reduces the quality of the popular drink by making it
cloudy.
- Calcium oxalate is
known to cause health hazardous kidney stones and for this reason it is
necessary to regulate the amount of oxalic acid in foodstuffs.
- Oxalic acid has
probably a key role in breakdown of plant cell walls and suppression of
plant defenses and thus facilitate invasion for the fungus.
