Chemical Formula: NaOHA

liases: Caustic soda, lye, caustic potash, flake alkali, etc.

Appearance: Typically white flakes or granules, with strong corrosive and hygroscopic properties, can absorb moisture and dissolve in water to form a basic solution.

PropertiesStrong Alkalinity: Sodium hydroxide completely dissociates in water into sodium ions and hydroxide ions, exhibiting strong alkalinity and can react with acids in neutralization reactions to produce salts and water.

Corrosiveness: It has a strong corrosive effect on skin, fibers, glass, ceramics, etc., so care must be taken when using it.

Hygroscopicity: Sodium hydroxide easily absorbs moisture in the air, making its surface damp, and it should be stored in a sealed container.

UsesIndustrial Applications: Widely used in the manufacture of paper, textiles, soap, cleaners, etc.

Household Uses: Commonly used in drain cleaners and cleaners, effectively removing grease and dirt.

Chemical Reactions: Can be used in neutralization reactions with acids, producing corresponding sodium salts.

Safety:Sodium hydroxide has strong corrosive properties, and protective gloves and goggles should be worn to avoid contact with skin and eyes. If contact occurs, flush with plenty of water and seek medical assistance immediately.

Sodium hydroxide is an important chemical, and understanding its properties and uses is crucial for safe use and effective application.
