Question

Валентность железа, входящего в состав соединения Fe(OH)3, равна 2 4 1 3

Answer 1

Ответ:

Валентность железа, входящего в состав соединения Fe(OH)3, равна 3

Answer 2

The statement you provided seems to be a list of numbers: 2, 4, 1, 3. These numbers do not directly correspond to the valency (valence) of iron (Fe) in the compound Fe(OH)3.

Iron can exhibit multiple oxidation states or valencies in various compounds, but for Fe(OH)3, the valency of iron is +3.

The compound Fe(OH)3 is called iron(III) hydroxide, where the "III" in parentheses indicates that iron has a valency of +3 in this compound.

So, to clarify, the valency of iron (Fe) in Fe(OH)3 is +3. The numbers 2, 4, 1, 3 mentioned in the statement do not relate to the valency of iron in this particular compound.
