- Substance
Potassium hydroxide pellets are white to off-white in color and exhibit a hygroscopic nature, meaning they readily absorb moisture from the air. The melting point of potassium hydroxide is approximately 360 °C, while its boiling point is around 1320 °C. The density of potassium hydroxide pellets is about 2.044 g/cm³. It is highly soluble in water, with a solubility of approximately 1 g in 0.5 mL of water at 20 °C, and it generates heat upon dissolution. The pellets have a strong alkaline pH, typically around 13-14 when dissolved in water.
