Yes, it does. Additionally, it leaves a phosphate coating on the metal that resists further rust. Phosphoric acid is also used to etch steel to open the pores to let the primer layer of paint adhere better.

∙ 14y agoThe only system I can imagine phosphoric acid as an inhibitor is in a alkaline system where alkalinity causes damage.
Otherwise, phosphoric acid is a relatively mild oxidizer (when compared to oxygen, chlorine and chlorinated compounds) and will oxidize most substance.
In the case of Rust, PHOSPHORIC ACID CAN NOT INHIBIT RUST FORMATION. It will cause more rust to develop. An environment must be created in order for rust to develop and one criteria is the presence of acid [in particular hydrogen ion].
Any chemical that will inhibit rust, and I must add for only a while not infinitely, is some alkaline solution. This is in accordance with Le Chatelier principle, that state that an alkaline solution will in essence reduce rust formation due to the high hydroxyl ion concentration.
Hope I was helpful.

What is phoshoric acid?
phoshoric acid is an mineral acid. It is a rust converter used to rust or dissolve things!
Is HClO4 or H3PO4 stronger?
weak acid Phosporic acid is mainly used as a rust remover, so its not that strong.
What is rust acid or alkali?
Rust is acid
What makes Coca-Cola rust nails?
The concentration of carbonic acid. Its what makes your mouth tingle. Also, it will eventually dissolve the nail.
What happens when you add acid to metal?
When you add a metal to an acid, it creates two items. It creates a type of metallic salt and it creates some hydrogen gas.

Compound.
Chemical formula Phosporic Acid?
Formula: H3PO4
Does vinegar remove rust or increase rust. Half the articles say remove the other half say promote. What's what?
I think that the point is: 1) if you have rust, then vinegar that contains acetic acids, will dissolve your rust 2) if the steel or iron doesn't have rust, then vinegar can rust the steel or iron 'cause it contains an acid. I means that acid will corrode steel or iron but even dissolve rust, that is an iron oxide.
What is the formula for 'phosporic acid'?
H3po4 Site is messing up again! All letters are capitalized in this formula.

How can I remove rust from metal water bottle?
crystalized oxalic acid.....10 parts water to 1 acid...dissolve and soak till rust is gone. This substance is poisonous so be careful and insert with hypodermic syringe if necessary...rinse carefully

Why sodas clean pennys?
Soda or carbonated drink had CO2 dissolved in water and form carbonic acid. The rust is dissolve in the acid solution thus leave coin a shiny surface.
