Question

С чем реагируют ? FeO Fe2O3 Fe(OH)2 Fe(OH)3

Answer 1

FeO - основный оксид. Взаимодействует с кислотами, с кислотными оксидами, водой, амфотерными оксидами и кислородом. Не взаимодействует с основаниями и основными оксидами.
Fe2O3 - амфотерный оксид. С кислотами, щелочью, оксидами неметаллов. Никто не взаимодействует с водой.
Fe(OH)2 - основание. Вступает в реакции с кислотами, солями, водой.
Fe(OH)3 взаимодействует с щелочами образуя комплексные соли, с кислотами.

Answer 2

FeO, Fe2O3, Fe(OH)2, and Fe(OH)3 are all chemical compounds containing iron (Fe) in different oxidation states and with different combinations of oxygen (O) and hydroxide (OH) ions.

FeO (Iron(II) oxide):

- FeO is also known as iron(II) oxide or ferrous oxide. - It is a black solid compound. - FeO is formed when iron reacts with oxygen in a limited supply. - The chemical equation for the reaction is: Fe + 1/2O2 → FeO. - FeO can be further oxidized to form Fe2O3. - FeO is used in the production of iron and steel.

Fe2O3 (Iron(III) oxide):

- Fe2O3 is also known as iron(III) oxide or ferric oxide. - It is a reddish-brown solid compound. - Fe2O3 is formed when iron reacts with oxygen in an excess supply. - The chemical equation for the reaction is: 4Fe + 3O2 → 2Fe2O3. - Fe2O3 is commonly known as rust and is responsible for the reddish-brown color of rusted iron. - Fe2O3 is used as a pigment in paints and ceramics.

Fe(OH)2 (Iron(II) hydroxide):

- Fe(OH)2 is also known as iron(II) hydroxide or ferrous hydroxide. - It is a greenish solid compound. - Fe(OH)2 is formed when iron reacts with water or hydroxide ions. - The chemical equation for the reaction is: Fe + 2OH- → Fe(OH)2. - Fe(OH)2 can be oxidized to form Fe(OH)3 or further oxidized to form Fe2O3. - Fe(OH)2 is used in the production of pigments and as a reducing agent in chemical reactions.

Fe(OH)3 (Iron(III) hydroxide):

- Fe(OH)3 is also known as iron(III) hydroxide or ferric hydroxide. - It is a reddish-brown solid compound. - Fe(OH)3 is formed when iron reacts with water or hydroxide ions in an excess supply. - The chemical equation for the reaction is: Fe + 3OH- → Fe(OH)3. - Fe(OH)3 is commonly found in nature as a mineral called goethite. - Fe(OH)3 is used as a pigment in paints and as a coagulant in water treatment.
