Question

Напишите уравнения реакций к цепочке превращений: FeSO4- Fe- FeSO4 - Fe(OH)2- FeSO4 а) первую реакцию рассмотрите как окислитеоьно восстоновительный процессб) третью реакцию запишите в полном ионном и сокращенном ионном видах ​

Answer 1

Ответ:

Fe+H2SO4=FeSO4+H2(стрелка вверх)

FeSO4+NaOH=Fe(OH)2(стрелка вниз)+Na2SO4

Fe(OH)2=FeO+H2O

FeO+H2=Fe+H2O

Объяснение:

я на нашёл знак стрелок поэтому написал бувами.надеюсь всё правильно!

Answer 2

FeSO4- to Fe-:

The transformation of FeSO4- to Fe- involves the reduction of Fe2+ to Fe0. This can be represented by the following equation:

FeSO4- + 2e- → Fe- + SO4^2- [[1]]

Fe- to FeSO4-:

The transformation of Fe- to FeSO4- involves the oxidation of Fe0 to Fe2+. This can be represented by the following equation:

Fe- + SO4^2- → FeSO4- + 2e- [[1]]

FeSO4- to Fe(OH)2-:

The transformation of FeSO4- to Fe(OH)2- involves the precipitation of Fe2+ ions with hydroxide ions. This can be represented by the following equation:

FeSO4- + 2OH- → Fe(OH)2- + SO4^2- [[1]]

Fe(OH)2- to FeSO4+:

The transformation of Fe(OH)2- to FeSO4+ involves the oxidation of Fe2+ to Fe3+. This can be represented by the following equation:

2Fe(OH)2- + 2H+ → 2FeSO4+ + 2H2O [[1]]

Third reaction in full ionic and net ionic forms:

The third reaction, FeSO4- to Fe(OH)2-, can be written in both full ionic and net ionic forms.

Full ionic equation: FeSO4- + 2OH- → Fe(OH)2- + SO4^2-

Net ionic equation: Fe2+ + 2OH- → Fe(OH)2- [[1]]
