What Is The Appearance Of Copper Cyanide?

Copper cyanide is a white to grayish-white powder or solid that may also appear as pale blue-green crystals. Its exact appearance can depend on factors such as its purity, particle size, and method of preparation. When exposed to air, copper cyanide can gradually darken in color due to the formation of copper oxide on its surface. It is sparingly soluble in water and insoluble in nonpolar solvents. Copper cyanide has a characteristic odor of hydrogen cyanide gas, which is toxic and potentially hazardous. Proper care should be taken when handling this compound to prevent exposure to its vapors or dust.
