Iron hydroxide Chemical Properties,Uses,Production
Physical Properties
Red-brown amorphous powder; density 3.40g/cm3; soluble in acids; insoluble in water and alcohol.
Uses
The compound is used in pigments and in water purifications.
Preparation
Iron(III) hydroxide is obtained as a brown gelatinous precipitate by adding a strong base to a solution of iron(III) salt:
FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
Chemical Properties
brown flocculant precipitate; used in water purification, manufacturing pigments [HAW93]
Physical properties
Red-brown amorphous powder; density 3.40g/cm3; soluble in acids; insoluble in water and alcohol.
Definition
YELLOW IRON OXIDE: a yellow-brown mineral,FeO.OH, crystallizing in the orthorhombicsystem. It is formed as aresult of the oxidation and hydrationof iron minerals or as a direct precipitatefrom marine or fresh water (e.g.in swamps and bogs). Most limoniteis composed largely of cryptocrystallinegoethite. Goethite is mined asan ore of iron.
