DESCRIPTION |
||||
|
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] |
