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 ignites on contact with the water surface, and burns with a blue flame. It also moves around on the surface, but it has never exploded like the sodium frequently does. Perhaps it is a matter of scale; the lump size that works safely in this demonstration is pea-sized: 7.5 mm diameter sphere, or 6 mm cube. on site leadership training for managers
