Sodium hydroxide liquid
Products Description
Sodium hydroxide is called caustic soda and lye, with the formula NaOH. It is a common ingredient in cleaners, detergents, and soaps. It could also be used to manufacture textiles, pulp, and paper.
It is a manufactured substance and very corrosive. At room temperature, sodium hydroxide is a white, odorless solid that absorbs moisture from the air. It can react violently with strong acids and with water.
Sodium hydroxide liquid is its form dissolved in water. It is highly corrosive and alkaline and is widely used in industry and laboratories.
Features
- Chemical Formula: NaOH
- Appearance: Colorless liquid, strongly alkaline.
- Solubility: Easily soluble in water, with significant exothermic reaction.
- pH value: In aqueous solution, the pH value is usually between 13-14, which is strongly alkaline.

Benefits
- Cleaner: Sodium hydroxide is often used in cleaners and stain removers to effectively remove grease, dirt, and other stubborn stains.
- pH adjuster: In water treatment and chemical reactions, sodium hydroxide is used to adjust the pH value and keep the solution alkaline.
- Chemical Synthesis: As a strong base, sodium hydroxide is used as a catalyst or reagent in many chemical reactions, especially when synthesizing organic compounds.
- Food Industry: In some food processing processes, sodium hydroxide is used for peeling, adjusting pH and as a preservative (subject to relevant regulations).
Application
- Industrial: Widely used in papermaking, textile, detergent, petroleum refining and water treatment industries.
- Laboratory: In chemical experiments, sodium hydroxide is often used in acid-base neutralization reactions and other chemical synthesis.
- Household Cleaning: As a powerful cleaner, sodium hydroxide can be used to clean drains and remove stubborn stains
