Quite effectively, actually. I was pickling a rusted bracket in nitric acid but I left it too long. The bracket was rust-free but the acid continued to eat the steel until it was paper-thin. You are better off using hydrochloric or phosphoric acid if you are prepping steel for painting. Both will open up the metal without eating it up.
Yes, nitric acid can dissolve iron oxide through a chemical reaction that involves converting the iron oxide into soluble iron nitrate. This process is known as dissolution or chemical etching. However, the reaction may take time and may require the acid to be heated or used in concentrated form.

Why iron does not react with nitric acid?
Iron does not react with nitric acid because nitric acid is a strong oxidizing agent that forms a protective oxide layer on the surface of iron, preventing further reaction. This oxide layer acts as a barrier, blocking the acid from reaching the iron underneath, thereby preventing the reaction to occur.
What happens when you adda nitric acid to iron?
When nitric acid reacts with iron, it produces nitric oxide gas, iron(II) nitrate, and water. The reaction is exothermic and may produce heat or gas. It is important to perform this reaction in a well-ventilated area because nitric oxide gas can be toxic.
Why iron is passive towards concentrated nitric acid?
Iron forms a protective oxide layer on its surface when exposed to air, which prevents further reaction with concentrated nitric acid. The oxide layer acts as a barrier, preventing the acid from coming into contact with the underlying iron metal, thereby making iron passive towards concentrated nitric acid.
What is iron hydroxide plus nitric acid?
When iron hydroxide reacts with nitric acid, it forms iron nitrate and water. The balanced chemical equation for this reaction is: Fe(OH)3 + 3HNO3 → Fe(NO3)3 + 3H2O
What is the balanced equation for iron oxide and nitric acid?
The balanced equation for the reaction between iron oxide (Fe2O3) and nitric acid (HNO3) is: Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O

What dissolves iron oxide?
Acids such as hydrochloric acid or sulfuric acid can dissolve iron oxide. Strong reducing agents like hydroxylamine can also dissolve iron oxide by reducing it to a soluble form.
What is the balanced equation for iron oxide and nitric acid?
The balanced equation for the reaction between iron oxide (Fe2O3) and nitric acid (HNO3) is: Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O
What acid can dissolve iron but not gold platinum and palladium?
Nitric acid can dissolve iron but not gold, platinum, and palladium. Nitric acid is a powerful oxidizing agent that reacts with iron to form soluble iron nitrate, while it does not react with noble metals like gold, platinum, and palladium.
What is the reaction of iron with dilute nitric acid concentrated nitric acid and very dilute nitric acid?
Iron reacts with dilute nitric acid to produce nitric oxide gas, iron(II) nitrate, and water. In concentrated nitric acid, iron reacts to form iron(III) nitrate, nitrogen dioxide gas, and water. In very dilute nitric acid, the reaction between iron and nitric acid is slow and may not be easily observable due to the low concentration of nitric acid.
What do you get when you add iron filings to nitric acid?
When you add iron filings to nitric acid, you will observe a chemical reaction where the iron reacts with the nitric acid to produce iron nitrate and release nitrogen dioxide gas. It's a redox reaction in which the iron is oxidized and the nitric acid is reduced.
What acid can quickly dissolve iron?
Hydrochloric acid (HCl) is commonly used to dissolve iron quickly due to its strong corrosive properties. It reacts with iron to form iron chloride and hydrogen gas, which leads to the dissolution of the iron material.
What is iron III oxide soluble in?
Iron (III) oxide is insoluble in water and most common solvents. However, it can react with acids to form soluble iron salts.
What will dissolve copper but not gold?
Iron is a highly reactive metal and most of the strong acids like sulfuric acid and nitric acid are able to dissolve it. Steel is less reactive than iron because it is an alloy but will get corroded and dissolved in nitric acid solution 50-70 %. See also the link below.
