Question

FeCl3→Fe(OH)3→Fe2O3→Fe(NO3)3→FePO4​

Answer 1

Ответ:

FeCl3→Fe(OH)3→Fe2O3→Fe(NO3)3→FePO4

FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl

2Fe(OH)3 → Fe2O3 + H2O

Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O

Fe(NO3)3 + H3PO4 → FePO4 + 3HNO3

Объяснение:

Answer 2

Відповідь:

FeCl₃ + 3KOH = Fe(OH)₃ + 3KCl

2Fe(OH)₃ = Fe₂O₃ + 3H₂O (t)

Fe₂O₃ + 6HNO₃ = 2Fe(NO₃)₃ + 3H₂O

Fe(NO3)3 + H3PO4 → FePO4 + 3HNO3

Answer 3

The chemical reaction sequence you've provided appears to represent the transformation of iron(III) chloride (FeCl3) into iron(III) phosphate (FePO4) via several intermediate reactions. Let's break down the reactions step by step:

1. FeCl3 (Iron(III) Chloride) reacts with NaOH (Sodium Hydroxide) to form Fe(OH)3 (Iron(III) Hydroxide) and NaCl (Sodium Chloride):

   FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl

2. Fe(OH)3 (Iron(III) Hydroxide) can undergo dehydration to form Fe2O3 (Iron(III) Oxide):

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

3. Fe2O3 (Iron(III) Oxide) reacts with nitric acid (HNO3) to form Fe(NO3)3 (Iron(III) Nitrate):

   Fe2O3 + 6HNO3 -> 2Fe(NO3)3 + 3H2O

4. Finally, Fe(NO3)3 (Iron(III) Nitrate) can react with sodium phosphate (Na3PO4) to form FePO4 (Iron(III) Phosphate) and sodium nitrate (NaNO3):

   Fe(NO3)3 + 3Na3PO4 -> FePO4 + 9NaNO3

So, the overall sequence of reactions is as follows:

FeCl3 → Fe(OH)3 → Fe2O3 → Fe(NO3)3 → FePO4

These reactions describe a series of chemical transformations from iron(III) chloride to iron(III) phosphate, with a few intermediate compounds involved along the way.
