Empirical Formula (Hill Notation): HNO3
CAS Number: 7697-37-2
Molecular Weight: 63.01

General description
A yellow coloration of the bottle has no influence whatsoever on the product quality.
Nitric acid (HNO3) is a highly corrosive strong mineral acid. 10%(v/v) nitric acid solution is useful for cleaning laboratory glasswares.[1] Reaction of HNO3 with various original and synthetic mineral dust/mineral oxide surfaces was studied in a low-pressure Knudsen reactor operating at 298K.[2]

Application
Nitric acid (HNO3) may be used for the removal of transition metal catalyst from the single-walled carbon nanotubes (SWNTs) during the purification of SWNTs.[3] It may be used in the trace determinations of Pb and Cd in natural waters by flame atomic absorption spectrometry.[1]

Puriss. p.a. nitric acid (≥65%) meeting ISO and Ph. Eur. specs. Suitable for trace metal analysis, glassware cleaning, and purification of carbon nanotubes.

May show yellowing without quality impact.
