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.
This is precisely what happens as the pH of water increases; that is the water becomes more alkaline. You may recall that alkalinity is caused by an increase in hydroxyl ions. An increase in hydroxyl ions (or alkalinity) pushes the equilibrium to the left and more unionized ammonia is formed.
