Colorless transparent liquid (when high purity), may be light blue due to trace impurities, extremely high pH value (1% solution pH is about 13.5), need to avoid contact with acids, metals (such as aluminum, zinc) and organic matter, need to be sealed to prevent absorption of CO₂ in the air to form potassium carbonate (K₂CO₃), high temperature may accelerate decomposition, recommended storage temperature ≤40℃.
