Iron, oxygen, hydrogen
Fe(OH)2 and Fe(OH)3
Iron hydroxide is a chemical compound made of iron (Fe) and hydroxide (OH) ions. It is commonly formed when iron reacts with water or hydroxide-containing compounds.
When ammonium hydroxide is added to iron (III) chloride, a brown precipitate of iron (III) hydroxide is formed. This brown color is characteristic of iron (III) hydroxide.
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.
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.
Iron hydroxide exists as a solid compound with varying states of hydration, such as iron(II) hydroxide (Fe(OH)2) and iron(III) hydroxide (Fe(OH)3). In its natural form, iron hydroxide usually appears as brown/yellow precipitates.
Iron, oxygen and hydrogen are found in Fe(OH)3.
It depends on whether it is iron (II) hydroxide or iron (III) hydroxide.
Iron hydroxide is a chemical compound made of iron (Fe) and hydroxide (OH) ions. It is commonly formed when iron reacts with water or hydroxide-containing compounds.
Rust consists of hydrated iron oxides Fe2O3·nH2O and iron oxide-hydroxide (FeO(OH), Fe(OH)3).
When ammonium hydroxide is added to iron (III) chloride, a brown precipitate of iron (III) hydroxide is formed. This brown color is characteristic of iron (III) hydroxide.

Potassium hydroxide, sodium hydroxide, magnesium hydroxide, iron oxide, also various other oxides and hydroxides and maybe even a little cyanide based salts(not very much).
After the reaction of iron with an acid a salt is formed, not a hydroxide.
Iron(III) hydroxide has the chemical formula Fe(OH)3.
When ammonium hydroxide reacts with a metal, such as magnesium or zinc, it can produce hydrogen gas. The metal displaces the ammonium ion in ammonium hydroxide, forming the metal hydroxide and releasing hydrogen gas in the process.
