  1. At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials.

  2. The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above.

  3. 14 Ιουλ 2023 · At a temperature of 20 °C, the solubility of sodium hydroxide (NaOH) in water is 109 grams per 100 grams of water. Additionally, the heat of solution for this process is -44.5 kJ mol -1 (kilojoules per mole).

  4. Sodium hydroxide is used in the home as a drain cleaning agent for clearing clogged drains. It is distributed as a dry crystal or as a thick liquid gel. The chemical mechanism employed is the conversion of grease to a form of soap. Soap is water-soluble, and can be dissolved by flushing with water.

  5. Sodium hydroxide. Formula: HNaO. Molecular weight: 39.9971. IUPAC Standard InChI:InChI=1S/Na.H2O/h;1H2/q+1;/p-1 Copy. IUPAC Standard InChIKey:HEMHJVSKTPXQMS-UHFFFAOYSA-M Copy. CAS Registry Number: 1310-73-2.

  6. 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

  7. 18 Νοε 2023 · NaOH Molar mass: 39.9971 g/mol Appearance White oily solid Odor: Odorless Density: 2.13 g/cm 3: Melting point: 318 °C (604 °F; 591 K) Boiling point: 1,388 °C (2,530 °F; 1,661 K)
