Nitric Acid










General Information:


Structure:



CAS Number: 7697-37-2

Molecular Weight: 63.01 g/mol

Appearance: Colorless to light yellow liquid


Nitric acid is a very strong acid as well as a strong oxidizing agent. In organic synthesis it is commonly used in nitration reactions. Nitric acid solutions with greater than 86% strength are called fuming nitric acid. Fuming nitric acid literally gives off visible fumes when the bottles are opened.




Common Uses:


Reagent in nitration reactions



Procedure excerpt:

To a mixture of the SM (30.0 g, 159 mmol) and concentrated H2SO4 (100 mL) at about -5 C was added dropwise HNO3 (11.0 mL, 174 mmol) over 20 min. The reaction . . .
