ChroMiuM hydroxide Usage And Synthesis
Chemical PropertiesGreen, gelatinous precipitate. Decomposes to chromic oxide by heat. Insoluble in water; soluble in acids and strong alkalies.
Physical propertiesBluish-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.
UsesGuignet’s green, catalyst, tanning agent, mordant.
PreparationChromium(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 ProfileA confirmed carcinogen. A poison. A powerful oxidizer. A powerful irritant of skin, eyes, and mucous membranes.
