Arthritis means joint inflammation.. It causes pain and swelling in the body's joints, such as the knees or hips. There are many types of arthritis, but osteoarthritis is the most common. Also known as degenerative joint disease or age-related arthritis, osteoarthritis is more likely to develop as people get older.
Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and inflammable liquid that boils slightly above room temperature, at 25.6 Â°C (78.1 Â°F).
Another toxic gas used in chemical suicides is hydrogen cyanide, though it is not as common because the consumer products needed for the reaction are less readily available. Hydrogen cyanide gas is created using an acid source and cyanide salts such as sodium cyanide or potassium cyanide.
