Sodium hydroxide has the formula NaOH, and is composed of the elements sodium Na, oxygen O and hydrogen H. It is considered a strong base, as it dissociates completely in water to form Na+ ion and OH ion. It is also known as lye or caustic soda. In this paper, a various empirical evidences of Sodium Hydroxide such as the chemical and physical properties, as well as the places and ways it is manufactured will be investigated, contemplated, and recorded down. The ultimate goal of this paper is to further understand the chemical NaOH, its uses and properties.


1. Since this solution is aqueous, the solute is sodium hydroxide (NaOH) and the solvent is water (H2O).
2. Sodium Hydroxide is a base solution. The formula is NaOH. The molecular weight is 40.0 g/mol.
3. The concentration of sodium hydroxide in is 0.50 mol/L.
4. Sodium hydroxide is produced (along with chlorine and hydrogen) via the chloralkali process. This involves the electrolysis of an aqueous solution of sodium chloride. The sodium hydroxide builds up at the cathode, where water is reduced to hydrogen gas and hydroxide ion:

2Na+ + 2H2O + 2eâˆ' â†' H2 + 2NaOH

5. Sodium hydroxide is also called lye, caustic soda or sodium hydrate. It is a strong alkali. Back then the Egyptians already used caustic soda to manufacture soaps. Later caustic soda was made from sodium carbonate.Caustic soda benefited from progress in the manufacture of sodium carbonate and the mastery of electrolysis technique.


A.) Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. It is used in the process of cotton fabrics, bundering and bleaching and metal cleaning.

B.) Sodium hydroxide breaks down with other chemicals when it is released to the atmosphere.When it is a solid it absorbs moisture easily. Sodium powered form is...
