Oxalic acid
is classified as a weak acid. It is weaker than H3O+ ion (water).
But it is
stronger than Acetic acid, Sulfurous acid, Nitrous acid, Benzoic acid etc.
Firstly it is an organic compound and generally organic compounds are not strong acids. Oxalic acid is also called as dicarboxylic acid. As it is an organic compound, it is called organic oxalic acid.
Oxalic acid = H2 C2 O4 or HOOC - COOH.
Disociates into Hydrogen oxalate ions HOOC-COO- : Ka = 5.4 * 10^-2 =======
Strong acids are those with Ka activity constant much more than 1.
Acids with Ka less than 1 are weak acids.
==================
Useful information:
Oxalic acid is a colorless crystalline sold and it dissolves well to a colorless solution in water. Oxalic acid is produced in our bodies by the metabolic processes. Organic oxalic acid combines with Calcium (organic in the body) to help digestive assimilation of Calcium and also in the contractions and relaxations that take place in the muscles of digestive tract. When organic oxalic acid is boiled or processed, it combines with Calcium in a harmful way and causes deficiency of Calcium.
