Question

FeCl3-->Fe(OH)3-->FeCl3-->Fe(OH)3-->Fe2(SO4)3

Answer 1

FeCl3+3NaOH=Fe(OH)3+3NaCl
Fe(OH)3+3HCl=FeCl3+3H2O
FeCl3+Ca(OH)3=Fe(OH)3+CaCl3
2Fe(OH)3+3H2SO4=Fe2(SO4)3+6H2O

Answer 2

Reaction: FeCl3 -> Fe(OH)3 -> FeCl3 -> Fe(OH)3 -> Fe2(SO4)3

The given reaction involves the conversion of FeCl3 to Fe(OH)3, followed by the conversion of Fe(OH)3 back to FeCl3, and then again to Fe(OH)3. Finally, Fe(OH)3 is converted to Fe2(SO4)3.

Let's break down the reaction step by step:

1. FeCl3 -> Fe(OH)3: The reaction between FeCl3 and a base (such as NaOH) can produce Fe(OH)3 as a precipitate. This reaction is an example of a neutralization reaction, where the base reacts with the acid (FeCl3) to form water and a salt (Fe(OH)3). The balanced equation for this reaction is:

FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl [[10]](https://portal.tpu.ru/SHARED/v/VVMAMONTOV/Tab1/Obchaya_ximiya.pdf)

2. Fe(OH)3 -> FeCl3: The conversion of Fe(OH)3 back to FeCl3 can be achieved by treating Fe(OH)3 with hydrochloric acid (HCl). This reaction is a reverse of the neutralization reaction mentioned above. The balanced equation for this reaction is:

Fe(OH)3 + 3HCl -> FeCl3 + 3H2O 3. FeCl3 -> Fe(OH)3: The process of converting FeCl3 back to Fe(OH)3 can be repeated by adding a base (such as NaOH) to FeCl3. This reaction is similar to the first step mentioned above. The balanced equation for this reaction is the same as the first step:

FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl 4. Fe(OH)3 -> Fe2(SO4)3: The final step involves the conversion of Fe(OH)3 to Fe2(SO4)3. This can be achieved by treating Fe(OH)3 with sulfuric acid (H2SO4). The balanced equation for this reaction is:

2Fe(OH)3 + 3H2SO4 -> Fe2(SO4)3 + 6H2O [[10]](https://portal.tpu.ru/SHARED/v/VVMAMONTOV/Tab1/Obchaya_ximiya.pdf)

In summary, the given reaction involves a series of conversions between FeCl3, Fe(OH)3, and Fe2(SO4)3, with the use of different reagents such as NaOH and HCl.
