Chromium(III) hydroxide (1308-14-1) |
| Hazard Information | Back Directory | [Chemical Properties]
Green, gelatinous precipitate. Decomposes to chromic oxide by heat. Insoluble in water;
soluble in acids and strong alkalies. | [Physical properties]
Bluish-green powder or green gelatinous precipitate; decomposes to chromium(III) oxide on heating; insoluble in water; soluble in dilute mineral acids when freshly prepared, becoming insoluble on aging; soluble in strong alkalis. | [Preparation]
Chromium(III) hydroxide may be prepared by precipitation from mixing ammonium hydroxide solution with a soluble chromium(III) salt, such as chromium(III) chloride or nitrate:
CrCl3 + 3NH4OH → Cr(OH)3 + 3NH4Cl. | [Toxics Screening Level]
The initial threshold screening level (ITSL) for chromium III hydroxide is 0.5 micrograms per cubic meter (μg/m3) based on a 24-hour averaging time. |
