Question

Осуществите превращения FeCl3->Fe(OH)3->Fe2O3->Fe2(SO4)3->Fe(OH)

Answer 1

FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

2Fe(OH)3 -> Fe2O3 + 3H2O

Fe2O3 + 3H2SO4 = Fe2(SO4)3 +3 H2O

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

Answer 2

Chemical Transformations of FeCl3

The chemical transformations of FeCl3 can be represented as follows:

1. FeCl3 → Fe(OH)3 - The reaction of FeCl3 with a base such as NaOH or KOH forms Fe(OH)3. - FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl.

2. Fe(OH)3 → Fe2O3 - When Fe(OH)3 is dehydrated, it forms Fe2O3, which is rust or iron(III) oxide. - 2Fe(OH)3 → Fe2O3 + 3H2O.

3. Fe2O3 → Fe2(SO4)3 - The reaction of Fe2O3 with sulfuric acid (H2SO4) forms Fe2(SO4)3. - Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O.

4. Fe2(SO4)3 → Fe(OH) - The reaction of Fe2(SO4)3 with a base such as NaOH or KOH forms Fe(OH)3. - Fe2(SO4)3 + 6NaOH → 2Fe(OH)3 + 3Na2SO4.

These reactions represent the chemical transformations of FeCl3 leading to the formation of Fe(OH)3, Fe2O3, Fe2(SO4)3, and back to Fe(OH)3.
