Modify: 2024-05-25. Description. 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.
May 10, 2024 · Chemical Safety Facts - Sodium Hydroxide (May 10, 2024) sodium hydroxide (NaOH), a corrosive white crystalline solid that contains the Na + ( sodium) cation and the OH − ( hydroxide) anion. It readily absorbs moisture until it dissolves. Sodium hydroxide is the most widely used industrial alkali and is often used in drain and oven cleaners.

Physical properties. Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition and boils at 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol. [14] Sodium hydroxide is insoluble in ether and other non-polar solvents.
