General
Oxalic acid is an organic compound with the formula C2H2O4. It is a colorless crystalline solid that forms a colorless solution in water. Its condensed formula is HOOCCOOH, reflecting its classification as the simplest dicarboxylic acid.
Its acid strength is much greater than that of acetic acid. Oxalic acid is a reducing agent and its conjugate base, known as oxalate (C2O2−4), is a chelating agent for metal cations. Typically, oxalic acid occurs as the dihydrate with the formula C2H2O4·2H2O.
It occurs naturally in many foods, but excessive ingestion of oxalic acid or prolonged skin contact can be dangerous.
Its name comes from the fact that early investigators isolated oxalic acid from wood-sorrel (Oxalis).

“The item came two days late, but this looked to be the fault of The Post Office not the seller as the outer cardboard box was damaged and the Post Office had put it in a bag with an apology note on it. The seller had sent it Post Office 48. Fortunately the inner tub was intact with no damage to it. It least it eventually turned up, so I am happy.”
