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 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.
Yes, oxalic acid can be titrated by HCl because oxalic acid is a diprotic acid and can react with HCl in a simple acid-base reaction. The titration involves determining the volume of acid required to neutralize the oxalic acid solution, which can be used to calculate the concentration of oxalic acid.
Oxalic acid is an organic compound, a diprotic acid, with the molecular formula H2C2O4.
we add sulpheric acid with oxalic acid to stable the ions when titrated against KMNO4
The chemical name of oxalic acid is ethanedioic acid.
Oxalic acid effectively removes rust from metal surfaces by forming a chemical reaction with the iron oxide in the rust, breaking it down and making it easier to scrub away. This process helps to dissolve and remove the rust, leaving the metal surface clean and restored.
Oxalic acid (one teaspoon) to remove rust and iron stains
The recommended concentration of oxalic acid for effectively removing rust from surfaces is typically around 10-15.
Oxalic acid is effective at removing rust 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.
The active ingredient in rust remover is usually phosphoric acid or oxalic acid, which work to dissolve and remove rust from metal surfaces.
Phosphoric acid is a chemical that effectively removes rust from metal surfaces.

Oxalic acid is commonly used as a cleaning agent for rust removal, as a bleaching agent for wood and other materials, and in some industrial processes like dyeing and tanning. It is also used in some household products like rust removers and stain removers.
Chemicals such as phosphoric acid, citric acid, and oxalic acid are effective in removing rust from metal surfaces. These acids work by breaking down the rust and allowing it to be easily wiped or scrubbed away.
Oxalic acid is commonly used as a rust remover, stain remover, and wood bleach. It is also used in some cleaning products and as a mordant in dyeing and printing textiles.
Oxalic acid is H2C2O4
