History - Nitric Acid

Nitric Acid has the name Aque Regina due to the fact that beacuse to its corrosive behavior, it is one of few "reagents" that can dissolve metals such as gold and platinum. Jabir ibn Hayyan The first known person to write a decription and discuss their method of sythesizing nitric acid was named Jabir ibn Hayyan (born in Persia c. 721 and died in Iraq c. 815) In his decription he says:

Nitric Acid

What we call ''concentrated nitric acid'' is actually a solution of 68% by weight HNO 3 in water (16M), and is often pale yellow as a result of photochemical decomposition which gives NO 2. By dissolving even more NO 2 into the pure material produces red '' fuming '' nitric acid, which is an extremely powerful acid and oxidising agent using in the semiconductor industry for cleaning silicon wafers.
