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. Reaction of HNO3 with various original and synthetic mineral dust/mineral oxide surfaces was studied in a low-pressure Knudsen reactor operating at 298K.

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. It may be used in the trace determinations of Pb and Cd in natural waters by flame atomic absorption spectrometry.

Other Notes

The article number 30709-4X2.5L will be discontinued. Please order the single bottle 30709-2.5L which is physically identical with the same exact specifications.
