Oxalic Acid PWD
Oxalic acid is an organic compound with the formula H2C2O4. This colorless crystalline solid is a dicarboxylic acid. In terms of acid strength, it is about 3,000 times stronger than acetic acid. Oxalic acid is a reducing agent and its conjugate base, known as oxalate (C2O42), is a chelating agent for metal cations. Typically oxalic acid occurs as the dihydrate with the formula H2C2O4·2H2O.
Transparant, colourless crystals. Hazard: Toxic by inhalation and ingestion, strong irritant.
Uses: general metal and equipment cleaning, purifying agent and intermediate for many compounds.
Oxalic acid's main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent), e.g. Bar Keepers Friend is an example of a household cleaner containing oxalic acid.
About 25% of produced oxalic acid is used as a mordant in dyeing processes.
It is used in bleaches, especially for pulpwood.
It is also used in baking powder.

Using Application :
Oxalic Acid is used extensively for boat cleaning, it can be used on timber, GRP and steel craft for the removal of rust and waterline stains and also to clean timber decks. For vertical applications oxalic can be mixed with wallpaper paste to make a thick solution, this mix will cling to any vertical surface and can be washed off with water.

In humans, oxalic acid has an oral (lowest published lethal dose) of 600 mg/kg (human).
The main toxicity of oxalic acid is due to the precipitation of calcium oxalate in the kidneys when urine becomes supersaturated with respect to this salt. Oxalic acid is also a metabolism product of the degradation of ethylene glycol if accidentally ingested and, as such, directly represents a danger for the kidneys in case of glycol poisoning.
First Aid
IF SWALLOWED -Give 1 or 2 glasses of water and call for medical assistance immediately.
EYE CONTACT - Wash with plenty of water for at least 15 minutes; Get medical attention promptly.
