- Substance
Potassium hydroxide flakes appear as white to off-white solid flakes that are highly hygroscopic. They have a melting point of approximately 360 °C and a boiling point of around 1320 °C. The density of potassium hydroxide is about 2.044 g/cm³. It is freely soluble in water, with a solubility of approximately 1 g in 0.5 mL of water at 20 °C, and it generates a significant amount of heat upon dissolution. The compound has a pH value of around 14 when dissolved in water, indicating its strong basicity.
