REACTION of trivalent nitrogen with the azide ion, usually called the ‘nitrite-azide reaction’, is generally known and has been a subject of recent detailed investigations 1–4. This azide reaction has ...

The vigorous reaction between copper metal and nitric oxide famously propelled chemist Ira Remsen into an esteemed career in research and education that spanned the turn of the 20th century. In a ...

Because nitric acid is stable, long-lived, and not photochemically reactive, it’s long been thought to be the final destination for reactive nitrogen species in the atmosphere. But those assumptions ...

Acids are reactive, and even weak acids like vinegar can wow students with their reactivity. But strong acids can really put on a show, dissolving otherwise relatively inert metals. And aqua regia, or ...

Modern fertilizer manufacturing uses the Haber-Bosch and Ostwald processes to fix aerial nitrogen as ammonia, then oxidize the ammonia to nitric acid. Having already created a Haber-Bosch reactor for ...
