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. WebPotassium hydroxide is used to raise the pH as part of the fish emulsion process but is neutralized when the liquid fish product is produced so no change in soil pH would be expected.
