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! _____ 0:00 - Formation of aqua regia (mixing nitric acid with hydrochloric acid) 0:35 - Synthesis of pure nitrosyl chloride 3:42 - NOCl Hydrolysis 4:05 - Chlorine vapors and acetylene 4:23 - Nitrosyl chloride and acetylene 4:37 - Burning magnesium in an nitrosyl chloride atmosphere 5:12 - Reaction with potassium iodide 5:42 - Reaction with Hydrogen sulfide 6:16 - Reaction with gold _____ Support me on Patreon!
