Sodium hydroxide is used to neutralize acids and as a source of sodium ions for reactions that produce other sodium compounds. In petroleum refining it is used to neutralize and remove acids. The reaction of cellulose with sodium hydroxide is a key step in the manufacturing of rayon and cellophane.
The acids in tomato juice or vinegar, on the other hand, do not completely dissociate in water and are considered weak acids. Similarly, strong bases like sodium hydroxide (NaOH) completely dissociate in water, releasing hydroxide ions (or other types of basic ions) that can absorb H + .
Sodium hydroxide is sometimes called caustic soda or lye. It is a common ingrediet in cleaners and soaps. At room temperature, sodium hydroxide is a white, odorless solid. Liquid sodium hydroxide is colorless and has no odor. It can react violently with strong acids and with water. Sodium hydroxide is corrosive.
Physical Properties of Sodium Hydroxide. Sodium Hydroxide in its pure form is a white crystalline solid. It is odourless. It is soluble in water, glycerol and ethanol. When solid sodium hydroxide is mixed with water, it results in a highly exothermic reaction. Has a higher viscosity than water about 78 mPas. It can form several hydrates.
Sodium hydroxide. Sodium hydroxide is an alkali which is also known as caustic soda. Caustic means "burning" and caustic soda takes its name from the way it can burn the skin. It has the chemical formula of NaOH. It is a base, meaning it has a high pH.
What is sodium hydroxide? Sodium hydroxide, also called caustic soda or lye, is a strongly corrosive manufactured chemical substance. Sodium hydroxide is especially useful for its ability to chemically alter fats in a process called saponification. It is used in industry as a chemical reagent, to make soap, and in cooking to cure some foods.
Apr 22, 2024 · Sodium hydroxide is an alkaline ingredient used in cleaning products like cleaners and detergents. It is highly water-soluble and absorbs moisture and carbon dioxide from the air. The dissolution of sodium hydroxide in water is a highly exothermic process that generates significant heat.
