Methoxide Composition

Methoxides are mainly organic salts and alkoxide. The organic salts are produced by a reaction between an organic acid (organic compound having acidic properties) and an inorganic base (a base that is composed of an inorganic compound). Alkoxide is the conjugate base of an alcohol. An organic group is bonded to a negatively charged oxygen atom in an alkoxide.
