The free potassium reacts with water to form potassium hydroxide, and the hydroxyl-ion concentration is determined by pH change. A particuarly useful pH range of 5 to 9 was selected. Colored crystals were produced by the action of potassium vapor on halide crystals and the experimental results of the analysis of the colored potassium chloride crystals are shown to be within the 95% confldence level.
