Question

Fe2O3- Fe2( SO4)3- Fe( OH)3 - Fe2O3

Answer 1

Fe₂O₃ + 3H₂SO₄ = Fe₂(SO₄)₃ + 3H₂O

Fe₂(SO₄)₃ + 6NaOH = 2Fe(OH)₃↓ + 3Na₂SO₄

2Fe(OH)₃ -----t°-----> Fe₂O₃ + 3H₂O

Answer 2

It seems like you've mentioned chemical compounds related to iron (Fe) and its different oxidation states. Let me break down the compounds you've mentioned:

1. Fe2O3: This is iron(III) oxide, also known as rust. It consists of iron atoms in the +3 oxidation state bonded with oxygen atoms.

2. Fe2(SO4)3: This is iron(III) sulfate. In this compound, iron is in the +3 oxidation state, and there are three sulfate ions ($SO_4^{2-}$) for every two iron ions.

3. Fe(OH)3: This is iron(III) hydroxide. Iron in this compound is also in the +3 oxidation state, and it's bonded with hydroxide ions ($OH^-$).

The first and third compounds you mentioned, Fe2O3 and Fe(OH)3, are different forms of iron(III) oxide, which can exist in various hydrated and unhydrated states. Iron(III) sulfate, Fe2(SO4)3, is a different compound where iron is bonded with sulfate ions.

If you have a specific question about these compounds or if you would like to know something specific about them, please let me know!
