- 1. Multiple Choice
Potassium cyanide is highly toxic. The moist solid emits small amounts of hydrogen cyanide due to hydrolysis, which smells like bitter almonds. Not everyone, however, can smell this; the ability to do so is a genetic trait. What is the IUPAC formula for potassium cyanide?KCNK(CN)2K2(CN)K2(CN)2 - 2.
