Sodium hydroxide is a strong alkaline chemical substance, commonly referred to as caustic soda or caustic soda. Its chemical formula is NaOH, which is a colorless and transparent liquid with corrosiveness and strong alkalinity.
The preparation of sodium hydroxide is usually obtained by electrolysis of sodium chloride solution, or by hydration process. Sodium hydroxide is widely used in industrial production, mainly for manufacturing soap, papermaking, artificial silk, synthetic fibers, dyes, catalysts, etc.
In addition, sodium hydroxide is also used in fields such as household cleaning agents and bleaches. It can neutralize acidic substances, remove stains and dirt, so it also has many uses in households. For example, it can be used to clean kitchens and bathrooms, as well as to clean kitchenware, stoves, toilets, etc.
It should be noted that sodium hydroxide is a highly alkaline substance with strong corrosiveness. Appropriate protective measures should be taken during storage and use to avoid skin contact and inhalation of dust. When using sodium hydroxide, protective equipment such as gloves and goggles should be worn to avoid harm to the human body.
