Nitric acid is a strong oxidizing, corrosive strong acid, belongs to the monomer inorganic strong acid, is one of the six strong inorganic acids, is also an important chemical raw material. In industry, it can be used to make fertilizers, pesticides, explosives, dyes, salts, etc.; in organic chemistry, the mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitrification reagent, and its aqueous solution is commonly known as nitric acid water or ammonia nitrogen water. The hazard symbol is O (Oxidizing agent) and C (Corrosive).

Save

Keep sealed and dry.

Use

In the electronics industry, used as a strong acidic cleaning corrosive, integrated circuit manufacturing for silicon cleaning, can be used in conjunction with hydrogen peroxide. The etching of organic materials is mainly used in the development of positive gel solution and graphic after the stripping solution (degumming agent) H202 a H2SO4
