과망가니즈산에 의한 옥살산 산화

개요

Permanganate oxidizes oxalate to CO₂ while Mn(VII) is reduced to Mn(II). This reaction is autocatalytic: the Mn²⁺ product catalyzes the reaction, so it starts slowly and accelerates dramatically. The purple permanganate is decolorized as the reaction proceeds. It is a classic redox titration used in analytical chemistry.

일상 속 예시

This reaction demonstrates autocatalysis: the first drops of permanganate decolorize slowly, but later drops disappear almost instantly.
