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.
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. It is highly corrosive to animal and vegetable tissue.
