Product Description
What Is Caustic Soda?
Caustic Soda (Sodium Hydroxide, NaOH) is a powerful alkaline substance commonly utilized in industries such as chemical manufacturing, water purification, and paper production. When dissolved in water, it forms a strongly alkaline solution and has a white solid appearance.
The chloralkali process, which electrolyzes sodium chloride (NaCl) to create sodium hydroxide, hydrogen gas, and chlorine gas, is the main production method.
The resulting solution is then concentrated and solidified to produce Caustic Soda.
