WebCyanide is a rapidly acting, potentially deadly chemical that interferes with the body’s ability to use oxygen. Cyanide can be a colorless gas or liquid, such as hydrogen cyanide (HCN) or cyanogen chloride (CNCl). Cyanide can also be a crystal (solid) form such as sodium cyanide (NaCN) or potassium cyanide (KCN). WebJun 27, 2024 · Find AEGL values in the table below using the chemical name or its CAS number.

If only a chemical's synonym is known, it is necessary to first find that chemical's CAS number to access the AEGL entry. To find the CAS number, enter the chemical …
WebpH values below 11 favor the formation of HCN, hydrogen cyanide that interferes with reaction (1). Hydrogen cyanide is a colorless and poisonous gas that, if released due to lower pH values, can quickly become deadly. Cyanide is also a relatively expensive chemical, so small losses in heap leaching can amount to large makeup costs over time.
