Question

используя необходимые реактивы и оборудование выполните следующие превращения 1:FeO-FeSO4-Fe(OH)2-Fe(NO3)2

Answer 1

1)FeO + H2SO4(разб.) = FeSO4 + H2O

2)FeSO4 + 2(NH3•H2O)(конц.) = Fe(OH)2↓ + (NH4)2SO4

3)2HNO3 + Fe(OH)2 = Fe(NO3)2 + 2H2O

Answer 2

Chemical Transformation Steps:

1. FeO to FeSO4: - The transformation from FeO to FeSO4 involves the addition of sulfuric acid. - The chemical equation for this transformation is: FeO + H2SO4 → FeSO4 + H2O.

2. FeSO4 to Fe(OH)2: - The transformation from FeSO4 to Fe(OH)2 involves the addition of a base, such as sodium hydroxide (NaOH). - The chemical equation for this transformation is: FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4.

3. Fe(OH)2 to Fe(NO3)2: - The transformation from Fe(OH)2 to Fe(NO3)2 involves the addition of nitric acid (HNO3). - The chemical equation for this transformation is: Fe(OH)2 + 2HNO3 → Fe(NO3)2 + 2H2O.

Overall Transformation:

The overall chemical transformation from FeO to Fe(NO3)2 involves the sequential addition of sulfuric acid, a base (such as sodium hydroxide), and nitric acid to the initial FeO compound.
