A solution of nitric acid, water and alcohol, nital, is used for etching metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure. [45] Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. [46]
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Ordinary commercial grade nitric acid consists of the constant boiling azeotrope of nitric acid and water, and contains 68% nitric acid. Mixtures of ordinary nitric acid in sulfuric acid therefore contain substantial amounts of water and are unsuitable for processes such as those that occur in the manufacture of trinitrotoluene .

It can be made by boiling the stoichiometric mixture of cerous nitrate, and sodium nitrate in nitric acid, and then evaporating at 40 °C. The crystals are clear rod shaped monoclinic with space group P 2/c. Crystal cell sizes are a=21.387 b=7.9328 c=15.184 β =90.657 V=2576 formulas per cell Z=8.
It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −). The anhydrous compound is unstable and may decompose explosively. [5] [6] It can be crystallized as a pentahydrate NaOCl·5H 2 O, a pale greenish-yellow solid which is not explosive and is ...

In 2002 however, anammox was found to play an important part in the biological nitrogen cycle, accounting for 24–67% of the total N 2 production in the continental shelf sediments that were studied. [31] [32] The discovery of anammox process modified the concept of biological nitrogen cycle, as depicted in Figure 2.
