WebJul 4, 2024 · A Potassium is a reductant, whereas methanol is both a weak acid and a weak base (similar to water). A weak acid produces H +, which can act as an oxidant by accepting an electron to form \(\frac{1}{2}\mathrm{H_2}\). This reaction, therefore, is an acid dissociation that is driven to completion by a reduction of the protons as they are released.
