Nitrous acid (molecular formula H N O 2) is a weak and monoprotic acid known only in solution, in the gas phase, and in the form of nitrite (NO − 2) salts. [3] It was discovered by Carl Wilhelm Scheele, who called it "phlogisticated acid of niter".
The nitrite ion has the chemical formula NO − 2.Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature.
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution.
Hyponitrous acid is a chemical compound with formula H 2 N 2 O 2 or HON=NOH. It is an isomer of nitramide, H 2 N−NO 2; and a formal dimer of azanone, HNO.. Hyponitrous acid forms two series of salts, the hyponitrites containing the [ON=NO] 2− anion, and the "acid hyponitrites" containing the [HON=NO] − anion.
The main use of sodium nitrite is for the industrial production of organonitrogen compounds. It is a reagent for conversion of amines into diazo compounds, which are key precursors to many dyes, such as diazo dyes.
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH.
Trọng Tấn (born 1976) is a Vietnamese singer and vocal music lecturer from Thanh Hóa.He specializes in traditional Vietnamese music and Vietnamese Red music.. Trọng Tấn started participating in arts performance and activities when he was still a student of Đào Duy Từ High School (Thanh Hóa).
Ammonium nitrite forms naturally in the air and can be prepared by the absorption of equal parts nitrogen dioxide and nitric oxide in aqueous ammonia. [1]It can also be synthesized by oxidizing ammonia with ozone or hydrogen peroxide, or in a precipitation reaction of barium or lead nitrite with ammonium sulfate, or silver nitrite with ammonium chloride, or ammonium perchlorate with potassium ...
