Benzidine copper acetate test

Japanese: ベンジジン酢酸銅試験 - ベンジジンさくさんどうしけん(英語表記)benzidine‐copper acetate test
Benzidine copper acetate test
A simple method for detecting hydrogen cyanide. Filter paper is soaked in a benzidine acetate solution, then dried, then soaked in an acetic acid solution, placed in a brown bottle and dried to create benzidine copper acetate test paper. When this test paper comes into contact with hydrogen cyanide, it turns blue, allowing hydrogen cyanide to be detected. However, chlorine, bromine, chloropicrin, etc. also turn the paper blue, so a confirmation test for hydrogen cyanide is required. [Hyuga Miho]
