| | 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. |
