일반 설명

Sodium sulfite is an inorganic sodium salt. Rapid-mixing method has been proposed to investigate kinetics of the reaction between oxygen and sodium sulfite.

애플리케이션

Sodium sulfite may be used in the preparation of wheat gluten films.

기타 정보

Nitrone spin traps such as 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) are commonly used for free radical detection. Though proven examples are rare, artifact formation must be considered. For example, the Forrester-Hepburn mechanism yields the same radical adduct as that formed by genuine radical
