Rust is Fe2O3 ....it can not be removed by
1.HCl
2.H2So4
3.Edta.....
but can remove by Oxalic Acid H2C2O4
Fe2O3(s) + 6 H2C2O4(aq) → 2 Fe(C2O4)3 3−(aq) + 3 H2O(l) + 6 H+(aq)
The chemical reaction is:
Fe2O3 + 3H2C2O4 = Fe2(C2O4)3 + 3H20
The cleaner The Works have two ingredients which made it eats rust. They are Oxalic Acid and Glycolic Acid, that's why this thing is so easy to wash the rust out of an object.
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
A mash of guava fruit is oxidized in the presence of vanadium pentoxide. This produces the diesters of oxalic acid which are then hydrolyzed to oxalic acid.
Rust refers to a reddish or yellowish-brown flaky coating of iron oxide. Some substances that remove rust from a nail are white vinegar, lime and salt, baking soda and oxalic acid.
we add sulpheric acid with oxalic acid to stable the ions when titrated against KMNO4
Oxalic acid (one teaspoon) to remove rust and iron stains
Oxalic acid can remove the rust due to its strong reducibility. The rust iron is ferric iron in the rusty spot, needless to dissolve into water. When touching oxalic acid, the ferric iron is reducted into bivalent iron which is dissolving in water. In addition, after using oxalic acid dihydrate to pickle ironmould on clothes, it is necessary to wash it with water a few times, not letting the excess of oxalic acid on clothes.

No. Oxalic acid is a weak acid.
You can clean rust spots off a porcelain sink easily with a product like Bar Keeper's Friend. This oxalic acid product can be made into paste that removes rust stains. One caution though: rust stains can be permanently set by using a chlorine-based cleaner.
Oxalic acid is H2C2O4
the basisity of oxalic acid is dibasic acid
no Oxalic acid is found in rhubarb
Try with a concentrated solution of oxalic acid; be careful, this acid is toxic.
2 is the valency of oxalic acid
It is an acid - Oxalic acid
how do prepare 0.1 N Oxalic acid
