General description

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.

A yellow coloration of the bottle has no influence whatsoever on the product quality.

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.
