Potassium, K. Reaction with water. When a small piece of potassium is added to water, it produces a hissing sound as it burns with a lilac flame. It also moves about quickly on the water surface. [ image ]. Hydrogen gas is given out in the reaction. The resulting alkaline solution will turn red litmus blue because of the potassium hydroxide formed.
When hard water is filtered through a trap containing potassium in chloride form, the chlorine ions bond to the minerals in the water and a chemical reaction happens. As a result, potassium ions enter the water, and corrosive elements like calcium chloride and magnesium remain trapped in the filter.
