Chemical compound

Mercury(II) nitrate is a toxic colorless or white soluble crystalline mercury(II) salt of nitric acid. It was also used to treat fur to make felt in a process called 'carroting'. The phrase 'mad as a hatter' is associated with psychological illness brought on by excessive exposure to mercury(II) nitrate. The practice continued in the United States until it was banned in December 1941 by The United States Public Health Service. It is made by reacting hot concentrated nitric acid with mercury metal; dilute nitric acid would produce mercury(I) nitrate. It is an oxidizing agent.
