14 Ιουλ 2023 · Sodium hydroxide is an ionic crystal composed of Na + cations and OH – anions. It is characterized by its colorless appearance, lack of odor, and high deliquescence. The substance exhibits a high degree of solubility in aqueous solutions, and its dissolution is accompanied by the release of thermal energy.
It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3, and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H 2 O and a liquid solution.
1 Its melting point is 318°C, and it has a boiling point of 1388°C. 2 It is highly soluble in water, with a solubility of 111 g/100 ml at 20°C. 3 The density of the substance is 2.13 g/cm 3. Production and Industrial Application.
