Sign in to saveAlso known as nitrites
The nitrite ion has the chemical formula . Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid.
Nitrite is a chemical compound (most commonly sodium nitrite) that contains nitrogen and oxygen and is widely used in industries ranging from pharmaceuticals to chemicals. It's also an important intermediate form of nitrogen that naturally cycles through the environment, and the term can refer to organic compounds containing a specific oxygen-nitrogen group.

亚硝酸盐是含有亚硝酸根（NO2−）阴离子的盐，有时会特指亚硝酸钠（NaNO2）。亚硝酸根离子是對稱的陰離子，两个N–O鍵的鍵長相同，∠O–N–O鍵角大约为120°。非直线型的亚硝酸根离子与臭氧是等电子体。 亞硝酸鹽可被氧化或還原，該產品一定程度上取決於氧化劑/還原劑和其強度；某些细菌可将亚硝酸盐还原为一氧化氮或氨，另一些细菌可以将亚硝酸盐转换成硝酸盐。亚硝酸盐愈硝酸盐的互相转化（氧化或还原）取决于含氧量、温度、酸鹼、细菌等因素而变化。 亚硝酸成的酯称为亚硝酸酯；有機化學的NO2基團存在於亞硝酸酯和硝基化合物。
