Question

Fe2O3FeCl3Fe(OH)3Fe(OH)2NO3Fe(NO3)3

Answer 1

Fe2O3 + 6HCl = 2FeCl3 + 3H2O

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

Fe(OH)3 + HNO3 = Fe(OH)2NO3 + H2O

Fe(OH)2NO3 + 2HNO3 = Fe(NO3)3 + 2H2O

Answer 2

The series of reactions you provided represents the conversion of iron(III) oxide (Fe2O3) to iron(III) nitrate (Fe(NO3)3). Here's a step-by-step breakdown of the reactions:

1. Fe2O3 → FeCl3: Iron(III) oxide reacts with hydrochloric acid (HCl) to form iron(III) chloride (FeCl3): Fe2O3 + 6HCl → 2FeCl3 + 3H2O

2. FeCl3 → Fe(OH)3: Iron(III) chloride reacts with a base, typically sodium hydroxide (NaOH), to form iron(III) hydroxide (Fe(OH)3): FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl

3. Fe(OH)3 → Fe(OH)2NO3: Iron(III) hydroxide is converted to iron(II) hydroxide by reducing it with a suitable reducing agent like sodium sulfite (Na2SO3): 2Fe(OH)3 + 3Na2SO3 → 2Fe(OH)2NO3 + 3Na2SO4

4. Fe(OH)2NO3 → Fe(NO3)3: Finally, iron(II) hydroxide nitrate reacts with nitric acid (HNO3) to form iron(III) nitrate: Fe(OH)2NO3 + 2HNO3 → Fe(NO3)3 + 2H2O

So, the overall reaction can be summarized as: Fe2O3 + 6HCl + 3NaOH + 3Na2SO3 + 2HNO3 → 2Fe(NO3)3 + 3NaCl + 3Na2SO4 + 3H2O

It's important to note that this series of reactions is a synthetic route and may involve the use of specific reagents and reaction conditions. Also, the reaction yields and the purity of the final product can vary depending on the reaction conditions and the quality of reagents used.
