Скачать или смотреть Nitrosyl Chloride: Aqua Regia’s Main Component

Nitrosyl Chloride is a yellow gas that is commonly encountered as a component of aqua regia, a mixture of 3 parts concentrated hydrochloric acid and 1 part of concentrated nitric acid. It is a strong electrophile and oxidizing agent.
Aqua regia (HNO3 + HCl) is well-known for its ability to dissolve gold. It's able to do this because it contains nitrosyl chloride - NOCl.
In this video I synthesized Nitrosyl chloride and demonstrated its reaction with gold!
