Sodium hydroxide (powder)
caustic soda Sodium hydroxide (NaOH), commonly known as caustic soda, caustic soda, caustic soda and caustic soda in Hong Kong, is a white crystal at room temperature, highly corrosive. Soluble in water, its aqueous solution is strongly alkaline, can make phenolphthalein red. Sodium hydroxide is a very commonly used alkali and is one of the essential drugs in the chemistry laboratory. Sodium hydroxide is easy to absorb water vapor in the air, and it must be sealed and stored with rubber stoppers. Its solution can be used as a washing solution.
