Fe(OH)2
Explanation:
Iron hydroxides are chemical compounds that appear as precipitates after alkalizing solutions containing iron salts, both in their valence or degree of oxidation (III) and (II).
Hydroxide, in both cases, is a gelatinous colloid of difficult filtration that can be considered a hydrated oxide, iron (II) hydroxide is whitish in color and requires more alkalinization, above 7.
