What is sodium hydroxide
Accepted Answer
Sodium hydroxide (NaOH), also known as lye or caustic soda, is a highly alkaline inorganic compound. It is a white solid that readily absorbs moisture and carbon dioxide from the air. Sodium hydroxide is highly soluble in water, producing a strongly alkaline solution that is often used in various industrial and household applications, such as:
Soap and detergent production: NaOH is used to saponify fats and oils, creating soap.
Paper production: NaOH is used in the pulping process to separate cellulose fibers from wood.
Chemical synthesis: NaOH is a key reagent in the synthesis of many chemicals, including pharmaceuticals and plastics.
Drain cleaner: The strong alkaline nature of NaOH can dissolve fats, oils, and hair, making it effective in unclogging drains.
Food production: In small quantities, NaOH can be used to adjust the pH of food or as a neutralizing agent.
It is important to note that sodium hydroxide is corrosive and can cause serious burns if it comes into contact with skin, eyes, or mucous membranes. Always handle it with care and wear appropriate protective gear.
