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.
is also called as dicarboxylic acid. As it
is an organic compound, it is called
organic oxalic acid.
= H2 C2 O4 or HOOC - COOH.
Disociates into Hydrogen oxalate ions HOOC-COO-
: Ka = 5.4 * 10^-2
acids are those with Ka activity constant
much more than 1.
Acids with Ka
less than 1 are weak acids.
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.
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.
organic oxalic acid is boiled or processed, it combines with Calcium in a
harmful way and causes deficiency of Calcium.
