No, it is hardly soluble in sodium hydroxide though it is amphoteric. It's better in (hydrochloric) acid.
No. as rust is caused by the oxidation process of: O2+2H2O+4e = 4OH in sodium hydroxide the hydroxide is already present making it harder to form and therefore making rust harder to form. Sodium hydroxide is a rust inhibitor.
Sodium hydroxide and hydrochloric acid can both react with steel wool to produce hydrogen gas. Sodium hydroxide may also corrode the steel wool by forming iron oxide. Hydrochloric acid can dissolve the steel wool as it reacts with the iron to form iron chloride.
The reaction between sodium and iron oxide would be a single displacement reaction, where sodium displaces iron from iron oxide to form sodium oxide and elemental iron. The balanced chemical equation for this reaction is 4Na + Fe2O3 -> 2Na2O + 2Fe.

The products of the reaction between iron II sulfate and sodium hydroxide are iron II hydroxide and sodium sulfate. The balanced chemical equation for this reaction is FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4.
To make iron sulfate, mix iron oxide with sulfuric acid. For iron hydroxide, mix iron sulfate with a strong base like sodium hydroxide to precipitate out the iron hydroxide. Iron oxide can be made by heating iron metal in the presence of oxygen.
When iron oxide is added to sodium hydroxide solution, a reaction occurs to form iron(III) hydroxide and water. The iron(III) hydroxide will appear as a brownish precipitate in the solution, while water remains as a liquid.
The iron(III) hydroxide is not soluble in water and doesn't react with sodium chloride.
When sodium hydroxide solution is added to a rusty nail, it reacts with the iron oxide (rust) to form soluble sodium ferrate, which helps to dissolve and remove the rust from the surface of the nail. This process is known as chemical dissolution, where the sodium hydroxide breaks down the rust into a soluble form that can be easily washed away.
No. as rust is caused by the oxidation process of: O2+2H2O+4e = 4OH in sodium hydroxide the hydroxide is already present making it harder to form and therefore making rust harder to form. Sodium hydroxide is a rust inhibitor.
If the iron oxide is Fe3O4 you can use a magnet.This is possible because magnetite has strong magnetic properties.For the separation from other iron oxides aluminium hydroxide can be dissolved in alkalis; iron oxides are not soluble in alkalis.
It is Iron III hydroxide (thats the brick red precipitate). It forms as well sodium chloride which is soluble in the water of the reaction and therefore you do not see.
iron chloride + sodium hydroxide = sodium chloride +iron hydroxide
Sodium hydroxide and hydrochloric acid can both react with steel wool to produce hydrogen gas. Sodium hydroxide may also corrode the steel wool by forming iron oxide. Hydrochloric acid can dissolve the steel wool as it reacts with the iron to form iron chloride.
Iron (II) hydroxide and sodium sulfate are formed when iron (II) sulfate is mixed with sodium hydroxide. Iron (II) hydroxide is a green precipitate that forms in the reaction.
The reaction between sodium and iron oxide would be a single displacement reaction, where sodium displaces iron from iron oxide to form sodium oxide and elemental iron. The balanced chemical equation for this reaction is 4Na + Fe2O3 -> 2Na2O + 2Fe.
