| | ChroMiuM hydroxide Usage And Synthesis |
| 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. | | Uses | Guignet’s green, catalyst, tanning agent, mordant. | | 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. | | Safety Profile | A confirmed
carcinogen. A poison. A powerful oxidizer.
A powerful irritant of skin, eyes, and
mucous membranes. |
